OPINION
CAMPBELL, Judge.
Appeal is taken from a conviction for capital murder. See Tex. Penal Code § 19.-03(a)(2). After finding appellant, William Alfred Robinson, guilty, the jury answered affirmatively the special issues required by Article 37.071(b) of the Texas Code of Criminal Procedure, and punishment was assessed at death. Direct review by this Court was then automatic. See Art. 37.-071(h). On original submission, we abated the appeal and remanded the cause to the trial court for an evidentiary hearing regarding appellant’s claim under Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986). Robinson v. State, 738 S.W.2d 673 (Tex.Cr.App.1987). The record of the Batson hearing, together with the trial court’s findings of fact and conclusions of law relevant thereto, have been forwarded to us. We will now affirm.
Viewed in the light most favorable to the verdict, the evidence1 at trial showed that shortly after midnight, on June 12, 1985, appellant and two male accomplices robbed Steven Michael Creasey and his female companion at gunpoint in the Montrose section of Houston. During the course of the robbery, Creasey was shot and killed, either by appellant or one of his accomplices. See footnote 2, post. After Creaséy’s death, appellant and the others abducted and sexually assaulted Creasey’s companion for approximately three hours. Creas-ey’s companion was then released.
In sixteen points of error, appellant challenges the trial court’s denial of a pretrial motion to suppress his inculpatory written statement; the trial court’s refusal to adopt an alternative method of jury selection; the trial court’s refusal to sustain appellant’s Batson claim; the trial court’s refusal to let him question four veniremen; the trial court’s granting of the State’s challenge of another venireman for cause; the trial court’s denial of a mistrial based on juror “misconduct;” the trial court’s denial of a special issue asking the jury whether it considered appellant’s inculpato-ry written statement; the trial court’s submission, to the jury, of the third special issue under Article 37.071(b); the trial court’s refusal, at the punishment stage, to instruct the jury regarding uncharged misconduct; the validity of the jury selection method utilized at his trial; the validity, as applied to his case, of Article 37.071(b); and the validity of the Texas death penalty scheme under the Eighth and Fourteenth Amendments.
In his first point of error, appellant argues the trial court erred in denying his pretrial motion to suppress an inculpatory written statement he gave to police shortly [222]*222after his arrest.2 Appellant contends the statement was obtained in violation of his right to counsel under the Fifth Amendment.3 More specifically, appellant contends that before he signed the statement he effectively requested the assistance of counsel, that the request was not honored, and that thereafter he did not initiate contact with the police.4
The record reflects that appellant filed a pretrial motion requesting suppression of, inter alia, “the written statement of the Defendant which ... was taken in violation of the Fourth, Fifth, Sixth and Fourteenth Amendments to the United States Constitution.” A pretrial hearing was held on the motion. At the hearing appellant requested suppression of the statement on the ground “the actions taken on behalf of the police officers and members of the D.A.’s Office and judiciary of this State ... violated [appellant’s] Fourth, Fifth, Sixth, and Fourteenth Amendments to the Constitution of the United States, those rights guaranteed to him under those amendments.” There is nothing else in the record, or in appellant’s brief to this Court, suggesting that the trial court and State’s counsel were ever apprised of the specifics of appellant’s objection to the admissibility of his written statement. On this record, then, we could properly overrule appellant’s first point of error as not preserved for appellate review. Rezac v. State, 782 S.W.2d 869, 870 (Tex.Cr.App.1990). In the interests of justice, however, we will proceed to explain why appellant’s argument has no merit.
At the pretrial hearing, only the State presented evidence, which consisted principally of the testimony of five witnesses. After the hearing, the trial court filed detailed written findings of fact and conclusions of law. Appellant does not now contest the accuracy of the fact-findings or their support in the record, and our examination of the record shows that they are indeed well-supported by the record.5
The trial court’s fact-findings may be summarized as follows: Appellant, then-27 years old, was arrested around 5:00 p.m., June 24, 1985, in Dallas. At the time of the arrest, the arresting officer explained to appellant his rights under Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966). That is, the arresting officer explained that appellant had the right to remain silent, that any statement he made could be used against him at trial, •that he had the right to an attorney before and during any questioning, and that if he could not afford an attorney one would be appointed for him. Immediately after his arrest, appellant was taken to the Dallas County jail facility, where a magistrate again explained to him his rights under Miranda.
Appellant was later taken to a Dallas police station, where, at approximately 1:30 a.m., June 25th, another police officer explained his Miranda rights to him a third time. After explaining those rights, the officer asked appellant whether he understood them, and appellant responded that he did. The officer then asked appellant whether he would give a statement regarding the murder of Steven Creasey. Appellant again responded that he would, and then he gave the statement, which was reduced to written form. After the state[223]*223ment was read back to appellant verbatim, the interviewing officer asked him whether he would sign it.6 Appellant responded with a question of his own: “Do I need to talk to a lawyer before I sign?” The officer answered that appellant could have a lawyer if he desired one, and then appellant stated that he was willing to sign immediately without a lawyer. Out of an abundance of caution, however, the officer refused to allow appellant to sign the statement, explaining to him that first he would have to be taken again before a magistrate, who would explain his Miranda rights yet again.
Shortly after 5:00 p.m. on June 25th, appellant was taken before a magistrate in Houston, after having been transported from Dallas. The magistrate explained to appellant his Miranda rights yet again and then asked appellant whether he understood those rights, and appellant stated that he did. The magistrate then read to appellant the statement he had given the night before in Dallas and again asked him whether he wanted to sign the statement without first consulting an attorney. Appellant responded that he did want to sign, even before consulting an attorney, and he did so.
In its fact-findings, the trial court found also that “[t]here was no evidence that the defendant ever appeared to be mentally or physically disabled or under the influence of any form of intoxicant” during the period in question, and that appellant was in no way coerced into making or signing the written statement. We note also that appellant does not argue to us that he had less than the normal use of his mental and physical faculties at the time he signed the written statement.
We turn now to a summary of the relevant legal principles. The Fifth Amendment privilege against self-incrimination protects an individual from being compelled by the state to be a witness against himself. See generally Holloway v. State, 780 S.W.2d 787 (Tex.Cr.App.1989). In Miranda, the Supreme Court established procedural safeguards to protect the exercise of the Fifth Amendment privilege from the inherently coercive effects of custodial interrogation. This is not to say, however, that the police are free to interrogate whenever they have given the requisite warnings, The Court in Miranda went on to hold that if, after the warnings are given, the defendant is interrogated and a statement obtained, it will be admissible at trial only if the prosecution demonstrates that the defendant waived his rights voluntarily, knowingly, and intelligently. 384 U.S. at 475, 86 S.Ct. at 1628. See also Tague v. Louisiana, 444 U.S. 469, 470-471, 100 S.Ct. 652, 653, 62 L.Ed.2d 622 (1980). Such waiver must be proven by a preponderance of the evidence. Colorado v. Connelly, 479 U.S. 157, 168, 107 S.Ct. 515, 522, 93 L.Ed.2d 473 (1986). If the prosecution shows that a suspect’s decision not to rely on his Miranda rights was uncoerced, that he at all times knew he could stand mute and consult a lawyer, and that he was aware the State could use his statements against him, the State’s burden of proof is met and waiver shown as a matter of law. Moran v. Burbine, 475 U.S. 412, 422-423, 106 S.Ct. 1135, 1141-1142, 89 L.Ed.2d 410 (1986).
On the other hand, if a suspect, after being given the Miranda warnings, does request the assistance of counsel, “interrogation must cease, and officials may not reinitiate interrogation without counsel present.” Minnick v. Mississippi, 498 U.S. 146, 153, 111 S.Ct. 486, 491, 112 L.Ed.2d 489 (1990). See Murphy v. State, 801 S.W.2d 917 (Tex.Cr.App.1991). The mere mention of the word ‘attorney’ or ‘lawyer’, without more, however, does not automatically invoke the right to counsel. Lucas v. State, 791 S.W.2d 35, 45 (Tex.Cr.App.1989). Where, as in the instant case, “a person’s invocation of his right to counsel is not clear and unambiguous, but is instead equivocal, the interrogating officers are not required to automatically cease the in[224]*224terview, but may continue questioning as long as the questions are specifically aimed at discovering whether the accused indeed wants to consult with counsel or wishes to proceed with the interview without benefit of counsel.” Id. at 46. See also Russell v. State, 727 S.W.2d 573 (Tex.Cr.App.1987).
Applying these principles to the case before us, it is plain that appellant’s written statement was not obtained in violation of his right to counsel under the Fifth Amendment. Appellant’s “request” for counsel was equivocal at best; further questioning was limited to ascertaining his wishes regarding presence of counsel; and his knowing and intelligent waiver of counsel was shown as a matter of law. Point of error number one is therefore overruled.
In point of error number two, appellant argues the trial court erred in denying his pretrial motion to suppress his written statement because it was obtained in violation of his Sixth Amendment7 right to counsel. Again, appellant argues that before he signed the statement he effectively requested counsel and that thereafter he did not initiate contact with the police.8
We note initially that point of error number two is no more preserved for our review than is point of error number one, and for the same reasons. See ante at 222. But, again, in the interests of justice, we will explain why appellant’s argument has no merit.
The Sixth Amendment provides that “[i]n all criminal prosecutions, the accused shall enjoy the right ... to have the Assistance of Counsel.” This right to counsel attaches at the formal initiation of adversary judicial proceedings “whether by way of formal charge, preliminary hearing, indictment, information, or arraignment.” Brewer v. Williams, 430 U.S. 387, 398, 97 S.Ct. 1232, 1239, 51 L.Ed.2d 424 (1977). If an accused is interrogated after the right to counsel has attached, and a statement obtained, the police may not use that statement against the accused unless counsel was present or waived when the statement was obtained. Brewer, supra at 399-404, 97 S.Ct. at 1239-1242. The burden is again on the State to prove such a waiver was made voluntarily, knowingly, and intelligently. Patterson v. Illinois, 487 U.S. 285, 292-293, 108 S.Ct. 2389, 2394-2395, 101 L.Ed.2d 261 (1988); Brewer, supra 430 U.S. at 404, 97 S.Ct. at 1242. Waiver is shown as a matter of law with regard to pretrial questioning if an accused (1) who has not yet retained or been appointed counsel (2) decides voluntarily not to rely on his right to counsel and (3) that decision is made with the understanding that he could remain silent and request a lawyer and that the State could use any statement he gave against him. Patterson, supra 487 U.S. at 297, 108 S.Ct. at 2397. If, on the other hand, an accused does request the assistance of counsel after his Sixth Amendment right has attached, then the police may not initiate any questioning of him or attempt to induce him to waive his right to counsel unless counsel is first provided. Michigan v. Jackson, 475 U.S. 625, 635-636, 106 S.Ct. 1404, 1410-1411, 89 L.Ed.2d 631 (1986). But, again, the mere mention of the word “attorney” or “lawyer” does not amount to a request for counsel. Lucas, supra at 45-46.
Assuming arguendo that appellant’s Sixth Amendment right to counsel had attached at the time he signed the written statement and that the giving of the statement constituted a “critical stage” to which the right applied, see Holloway, supra at 791 n. 3, we still have no difficulty determining that right was not infringed. Appellant never clearly requested counsel, and the State proved his knowing [225]*225and intelligent waiver as a matter of law. Point of error number two is overruled.
Appellant contends in point of error number five9 that the trial court erred "in refusing an alternative method of jury-selection that would insure a representative cross-section of the community.” More specifically, he argues that the jury wheel method used to select the venire was invalid because it failed to “insure[ ] ... a veni-re comprised of a representative cross-section of the community” in violation of unspecified “equal protection guarantees” as well as unspecified protections provided by Article 1, §§ 9 and 10, of the Texas Constitution.
The record reflects that on the fourth day of jury selection, appellant’s counsel complained to the trial court that only two of the first 26 veniremen brought to the courtroom for examination were black, although the population of Harris County was, at the time of trial, approximately 20 percent black. Shortly thereafter, defense counsel moved that the trial court modify the jury selection method:
DEFENSE COUNSEL: I would ask the Court, further, ... to take notice of the demographics of the voter-registration lists from which jurors are selected; that a more equitable way, in order to obtain balance of the prospective jurors here— and I’m not sure how we get the ones that we’re getting. But to go over to the central jury room without having access to their background data. The State picked three and we simply picked three from the faces or any other equitable method, to obtain a fair cross-section of the veniremen who constitutionally vote in this State of Texas, so that this defendant [will] get a jury of his peers.
THE COURT: That’s denied.
There is nothing in the record or in the briefs suggesting that appellant specified to the trial court and State’s counsel any constitutional or statutory provisions in support of his motion. Moreover, appellant has not specified to this Court any particular constitutional or statutory protections in support of his argument. We hold, therefore, that any error has not been preserved for our review. Rezac, supra at 870; Pierce v. State, 777 S.W.2d 399, 416 (1989), cert. denied, 496 U.S. 912, 110 S.Ct. 2603, 110 L.Ed.2d 283 (1990). Point of error number five is overruled.
In his sixth point of error, appellant, relying upon Batson v. Kentucky, supra, argues the trial court erred in denying his pretrial motion to quash the jury based on the prosecutors’ peremptory strikes of four black veniremen. Appellant argues that he made out a prima facie showing of unconstitutional racial discrimination and that the prosecutor failed, as a matter of law, to rebut that prima facie showing.
At the Batson hearing, the State and appellant stipulated, inter alia, that appellant is black; that twelve of the 81 veniremen were black; that the two prosecutors at trial challenged four black veniremen for cause (successfully) and six blacks (veniremen Hodge, Broussard, Sampson, Pollard, King, and Sims) peremptorily; that appellant struck one black peremptorily; and that one black served on the jury. Appellant relied upon this stipulated evidence to make his prima facie case. Although the trial court was not satisfied that a prima facie case of racial discrimination had been made, it nonetheless invited the State to provide neutral, relevant explanations for the challenged peremptory strikes.
The State accepted the trial court’s invitation and presented the testimony of the two men who had served as prosecutors at appellant’s trial. The first prosecutor testified that he peremptorily struck venireman Hodge because “she was very equivocating as far as whether she could actually participate as a juror on a [capital] case and assess the death penalty” and because “she indicated she thought premeditation should be a necessary prerequisite before the death penalty was assessed.” He testified [226]*226next that he struck venireman Broussard because of Broussard’s statement “that he did not feel that capital punishment was just and necessary [or had ever] been effective in preventing crime.” He testified also that he struck venireman Sampson because she “waffled back and forth” “about whether she could participate in assessing the death penalty.” Finally, the first prosecutor testified that he peremptorily struck venireman Pollard because “it turned out Mr. Pollard himself had been prosecuted for murder [and had] been convicted.”
The second prosecutor testified that he struck venireman King peremptorily because King “indicated ... that he did not believe in the death penalty,” and that he struck venireman Sims because Sims indicated “he could only give a death penalty on premeditated murder.”
At the conclusion of the Batson hearing, the trial court stated on the record that he found the State’s explanations for the challenged peremptory strikes to be “neutral, relative, clear, and legitimate as required by Batson and not racially motivated.”
The equal protection clause of the Fourteenth Amendment prohibits purposeful racial discrimination by the State in its ■ use of peremptory strikes. Batson v. Kentucky, supra 476 U.S. at 84, 106 S.Ct. at 1716; see generally Williams v. State, 804 S.W.2d 95 (Tex.Cr.App.1991); 2 LaFave & Israel, Criminal Procedure § 21.3 (Supp. 1990). “[A] criminal defendant may object to race-based exclusions of jurors effected through peremptory challenges whether or not the defendant and the excluded juror share the same race.” Powers v. Ohio, — U.S. -, 111 S.Ct. 1364, 113 L.Ed.2d 411 (1991). To establish a prima facie case10 of purposeful discrimination under Powers and Batson,
the defendant is entitled to rely on the fact, as to which there can be no dispute, that peremptory challenges constitute a jury selection practice that permits those to discriminate who are of a mind to discriminate. [Next], the defendant must show that [this] fact[] and any other relevant circumstances raise an inference that the prosecutor used that practice to exclude the veniremen from the petit jury on account of their race....
In deciding whether the defendant has made the requisite showing, the trial court should consider all relevant circumstances. For example, a “pattern” of strikes against black jurors included in the particular venire might give rise to an inference of discrimination....
Once the defendant makes a prima fa-cie showing, the burden shifts to the State to come forward with a neutral explanation for challenging [the] jurors [in question]. Though this requirement imposes a limitation in some eases on the full peremptory character of the historic challenge, we emphasize that the prosecutor’s explanation need not rise to the level justifying exercise of a challenge for cause_ The prosecutor ... must articulate a neutral explanation related to the particular case to be tried. The trial court then will have the duty to determine if the defendant has established purposeful discrimination.
Batson, supra 476 U.S. at 96-98, 106 S.Ct. at 1722-1724 (citations and some quotation marks omitted). “Since the trial court’s findings ... largely will turn on evaluation of credibility, a reviewing court ordinarily should give those findings great deference.” Id. at 98 n. 21, 106 S.Ct. at 1724 n. 21. Indeed, a reviewing court must view the evidence presented at the Batson hearing in the light most favorable to the trial court’s ruling, and must not disturb the trial court’s findings unless they are clearly erroneous, i.e., unless the reviewing court is left with a firm conviction that a mistake has been committed. Whitsey v. State, 796 S.W.2d 707, 721 (Tex.Cr.App. 1990) (op. on reh’g).
[227]*227Assuming arguendo that appellant made a prima facie showing at the Batson hearing, and viewing the evidence presented at that hearing in the light most favorable to the trial court’s finding of no purposeful discrimination, we conclude that the trial court’s finding is not clearly erroneous. The prosecutors’ explanations for their peremptory strikes were plainly of the variety previously upheld by this Court. See Tennard v. State, 802 S.W.2d 678, 681-682 (Tex.Cr.App.1990); DeBlanc v. State, 799 S.W.2d 701, 711-713 (Tex.Cr.App.1990); Keeton v. State, 749 S.W.2d 861, 870 (Tex. Cr.App.1988). Point of error number six is overruled.
In points seven through ten, appellant complains of the trial court’s refusal at voir dire to allow him to question veniremen Davis, Edmonds, Webster, and Carroll before they were excused for cause. See Drinkard v. State, 776 S.W.2d 181, 184-188 (Tex.Cr.App.1989); Perillo v. State, 656 S.W.2d 78, 81-82 (Tex. Cr.App.1983). The record reflects that the four veniremen were excluded for cause, because of their beliefs regarding the death penalty, immediately after examination by the prosecutor.
We need not reach the merits of appellant’s argument, because the record also reflects that he did not lodge a timely and specific objection to the trial court’s refusal to allow further questioning. Thus, any error has not been preserved for our review. Crane v. State, 786 S.W.2d 338, 345 (Tex.Cr.App.1990). Points of error seven through ten are overruled.
Appellant maintains in his twelfth point of error that the trial court violated his Sixth Amendment right to an impartial jury when it excused venireman Seymore for cause because of Seymore’s bias against the death penalty. Appellant argues that when Seymore’s answers to the voir dire questioning are examined as a whole, they reveal “that he could follow the law and apply it to the facts.”
The relevant portions of the voir dire record are as follows:
Q: [by the Court] ... Do you yourself have any conscientious, religious, or moral scruples against the infliction of death as a punishment for crime in a proper case?
A: No, I don’t.
* * * * * *
Q: [by prosecutor] I guess the first thing I’d like to find out [is] where you think capital punishment fits into our system of justice?
A: I feel like someone, ..., if they kill someone and they’re also a threat to come back into society to kill someone, they should be given the death penalty.
Q: ... Do you feel like if you were selected as a juror, you could participate and sentence someone to the death penalty?
A: No, not personally, to be honest with you.
Q: ... Can you imagine any set of facts ... in which, if you were selected as a juror, you could return a verdict that resulted in the death penalty?
A: No, not right offhand.
Q: ... What I need to find out is this: If you feel like if you were selected as a juror, you are going to always, regard-léss of the facts, ..., you are always going to vote in such a way that the person does not receive the death penalty?
* * * * ⅜ *
A: What I’m saying is, I probably couldn’t vote to have someone given the lethal injection.
Q: ... [C]an you imagine ever ... participating as a juror in which, by your verdict, the judge sentenced somebody to die by lethal injection?
A: No.
Q: ... Are you telling me that because of your personal feelings, you could never answer both of those [special issues] yes—
A: Yes.
Q: —knowing that the result will be that ... Mr. Robinson will receive the death penalty?
A: That’s correct.
* * * * * *
[228]*228Q: [by the Court] Mr. Seymore, would your answers be the same no matter what the facts and circumstances of the case might reveal to you?
A: Yes, it would be, Your Honor.
Q: Could you ever participate with eleven other jurors in answering those two questions yes, knowing that the defendant would receive the death penalty, regardless of what the facts in the trial might be?
A: No, I couldn’t, Your Honor.
* * * * * *
Q: [by defense counsel] Now I need to know: Is there a proper set of circumstances in your mind where, if the State — you were sitting as a juror— where the State brought you ample evidence to prove to you beyond a reasonable doubt that those two questions should be yes and you knew they should be yes ..., would you follow the law and answer them yes?
A: To the best of my ability, I would.
* * * * * *
Q: [by the Court] Knowing, Mr. Sey-more, that if you and eleven others each answer both of those questions yes, the defendant is going to receive the death penalty?
A: If the State says I have to serve on the jury and given this — given the proper case, Your Honor, and listen to the evidence, I — I would have to, I guess, vote yes.
* * * * * *
Q: Would you always automatically answer those two questions or one or the other of them in' such a way that would prevent the defendant on trial from receiving the death penalty, no matter what the facts of the case may be?
A: No, I could not.
Q: No, you could not, what?
A: I could not vote for the man to receive the death penalty. I could vote for the man to receive life in prison.
* * * * * %
Q: ... If both of those questions are answered yes, by a unanimous verdict, it’s death. If either one is answered no, it’s life imprisonment.
A: I would always have to vote for a life sentence. I could never personally vote to have a man put to death.
* * * sfc * sf
The Court: You’re excused, sir.
[[Image here]]
Defense Counsel: Our position, Your Honor, is that he was qualified under ... [Wainwright v.J Witt.
The Court: The record will certainly reflect your objection.
The State may challenge for cause any venireman who “has a bias or prejudice against any phase of the law upon which the State is entitled to rely for conviction or punishment.” Tex.Crim.Proc. Code art. 35.16(b)(3). Because of the Sixth Amendment right to an impartial jury, however, a venireman may not be challenged for cause based on his views about the death penalty unless those views would substantially impair the performance of his duties as a juror in accordance with his instructions and oath. Wainwright v. Witt, 469 U.S. 412, 424, 105 S.Ct. 844, 852, 83 L.Ed.2d 841 (1985); see 2 LaFave & Israel, Criminal Procedure § 21.3 at 733 (1984 & Supp.1990). A trial court’s decision to sustain such a challenge for cause is due great deference and will not be disturbed on appeal so long as the venireman’s testimony reasonably indicated that he would be unable to do his task well enough if selected. Goodwin v. State, 799 S.W.2d 719, 731 (1990); Hernandez v. State, 757 S.W.2d 744, 753 (Tex.Cr.App. 1988).
Applying the appropriate standard to the record in this case, we perceive no error. See Crane v. State, supra at 344. Point of error number twelve is overruled.
In point of error number three, appellant argues the trial court erred in denying his motion for mistrial after it was learned that a juror “had received evidence outside the record” of uncharged misconduct on his part. Appellant maintains that the juror became “disqualified” to serve [229]*229once she “received” the “evidence” in question.
The facts relevant to this issue are as follows: At the close of the evidence at the guilt/innocence phase, appellant’s counsel informed the trial court that an article regarding appellant’s trial had appeared the previous day in the Houston Chronicle newspaper. Defense Counsel told the Court he was concerned about the article because it did “not accurately reflect the testimony” of the State’s key witness. He then requested the court “to make inquiry of the jurors as to whether or not they read that specific article.” The trial court complied with appellant’s request and questioned each juror under oath, individually, and out of the presence of the others. Only Juror Romano testified she was aware of the article:
Q: [by the Court] During your service as a juror, have you read an article that appeared in the Houston Chronicle October 29,1985, concerning this case, written by a reporter, Mr. John Makeig?
A: No, I did not read it. But I have to tell you one other thing. My sister did and accidentally said something to me.
Q: Tell me what she said.
A: She said that she read where the third man had been killed by the other two.11
The Court: Any questions, [defense counsel]?
Defense Counsel: At this time I just move for a mistrial, Your Honor.
The Court: Any questions, [prosecutor]?
Q: [directed to Juror Romano, by the prosecutor] Ms. Romano, from your listening to the testimony of the last three days, do you recall the Judge instructing that you would be reaching any verdict you might have in this case based upon the evidence you were presented from the witness stand and the law as the Judge would instruct you?
A: Yes.
Q: Anything not legally admissible or competent evidence you would not consider for any purpose; is that correct?
A: Yes.
Q: This would be just as when we talked in voir dire about the issue if you heard testimony concerning a confession and if a jury decided the confession was not proper, you realize the law says you would have to set aside the fact you had heard that confession?
A: Yes. In fact, when she said that, I said, “Don’t tell me anything. I’m not supposed to know it.” She didn’t know she was saying anything.
Q: Do you understand and recall there has been no testimony in this case regarding how [the alleged accomplice] met his demise?
A: That’s right.
Q: Would you be able to tell the Judge you can follow his instructions as he has told you and base whatever verdict you may reach solely upon the evidence you have heard and not on anything else you may have heard?
A: The only thing I did hear about his demise was what I heard this afternoon.
Q: All right. In other words, any verdicts you reach in this case would be based upon your interpretation of the evidence you heard from the witness stand?
A: Yes.
Q: And it would not be affected in any form or fashion by anything else you may have heard?
A: No.
Q: [by the Court] You understand the evidence he is discussing with you is only the evidence you heard in the courtroom?
A: Yes.
Q: If you have to be honest, I have to be honest. Can you set that aside and not consider it at all?
A: Yes.
The Court: Any questions?
Defense Counsel: Re-urge.
[230]*230The Court: It will be denied.
* * * * * *
Defense Counsel: The basis of my request for a mistrial is that it introduces the extraneous offense of the killing of [the accomplice] to the jury, and that’s the basis of it.
The Court: All right, sir.
Defense Counsel: I understand it is denied.
The Court: Yes, sir. Before you bring [the next juror], bring me Ms. Romano back.
Q: [directed to Juror Romano, by the Court] I just want to ask you a quick question, Ms. Romano. The conversation you had with your sister, did you give that conversation or any of the parts of it to any other juror?
A: No, sir.
Q: You haven’t mentioned it to them at all?
A: No, .sir.
Q: You are instructed not to do so.
A: Yes, sir.
For an accused to have a fair trial, the jury must decide his case on the basis of the evidence presented at trial. Therefore, when jurors converse with unauthorized persons about a case, injury to the accused is presumed and a mistrial may be warranted. See Tex.Crim.Proc.Code art. 36.22; Tex.R.App.Proc. 30(b)(7). The State may rebut the presumption of harm, however. Thomas v. State, 699 S.W.2d 845, 853 (Tex.Cr.App.1985). Here, the information conveyed to Juror Romano by her sister, brief though it was, was clearly prejudicial to appellant. Romano stated under oath, however, that she did not tell any other jurors about her sister’s statement and that the statement would not influence her in reaching a verdict. The trial judge was in a position to observe Romano’s testimony, and he apparently chose to believe it. On this record, we cannot say the trial court abused its discretion in denying a mistrial.12 See Thomas. Point of error number three is overruled.
In point four appellant contends the trial court erred in denying his requested special issue asking the jury whether it considered appellant’s inculpatory written statement. Appellant argues that “[d]enial of such [special issue] in these circumstances denie[d] the convicted defendant his full right to present mitigating evidence or argument at the punishment, phase and his right to challenge the sufficiency of [the] evidence on appeal, and therefore necessarily violatefd] due process and due course of law guarantees.”
The record reflects that the evidence presented at the pretrial suppression hearing regarding the acquisition of appellant’s written statement (see above) was presented again at trial. The trial court, apparently out of an abundance of caution, instructed the jury pursuant to Tex.Crim.Proc.Code art. 38.23 anyway. That is, after being given the relevant law, the jury was instructed to disregard appellant’s written statement if it believed, or had a reasonable doubt, that the statement was obtained unlawfully.
Before the charge was given to the jury, appellant requested that a special issue be included asking the jury whether it considered the written statement or whether it found the statement unlawfully obtained. At the time he made the request, however, appellant made no argument and cited no authority — constitutional, statutory, or otherwise — in support of his novel request. Any error has not, therefore, been preserved for our review. Rezac v. State, supra at 870. Point four is overruled.
In point of error number thirteen, appellant argues the trial court erred in submitting to the jury at the punishment stage, over his objection, the Article 37.-071(b)(3) special issue, which asks: “[I]f raised by the evidence, whether the conduct of the defendant in killing the deceased was unreasonable in response to the [231]*231provocation, if any, by the deceased.” Appellant argues that the special issue was unwarranted because it was not raised by any evidence at trial.
By the plain terms of Article 37.071(b)(3), the trial court shall submit the third special issue “if raised by the evidence.” In the instant case, ample evidence was presented from the testimony of witnesses and from a written statement made by the appellant himself that the deceased had somehow managed to provoke his own death, by disobeying instructions from the appellant and his cohorts and, at one point, approaching appellant in a threatening manner. It therefore appears that the trial judge had no choice but to give the third special issue. See Johnson v. State, 629 S.W.2d 731, 733 (Tex.Crim.App.1981). Point thirteen is overruled.
In his fifteenth point of error, appellant argues the trial court erred in refusing his requested instruction, at the punishment stage, regarding evidence of appellant’s uncharged misconduct.13 The requested instruction would have instructed the jury that it could not consider any uncharged misconduct evidence with respect to special issue number one (deliberateness). See Tex.Crim.Proc.Code art. 37.-071(b).
The trial court did not err. Juries are free to consider uncharged misconduct evidence when answering special issue number one. Harris v. State, 790 S.W.2d 568, 589 (Tex.Cr.App.1989); Rector v. State, 738 S.W.2d 235, 242-243 (Tex.Cr.App.1986), cert. den., 484 U.S. 872, 108 S.Ct. 202, 98 L.Ed.2d 153 (1987). Point fifteen is overruled.
In point eleven appellant contends that the Texas “death penalty jury selection process [is] unconstitutional as applied” to his case because it “result[ed] in mostly white venireman being qualified for potential service.” More specifically, appellant argues that the “selection process” violated federal and state guarantees of due process and equal protection of the laws because “black veniremen [were] struck for cause in a much higher ratio (50%) than blacks [were] represented in the venire (15%).” (Emphasis added.) We need not reach the merits of this argument, however, because it was not raised below. Point of error number eleven is overruled.
Appellant maintains in point fourteen that Article 37.071, as applied in this case, violates state and federal guarantees against cruel and unusual punishment because “there is no mechanism to charge the jury on mitigation-type evidence when the Defendant is not the killer-in-fact.” See footnote 2, ante. The gist of appellant’s argument seems to be that the jury could have found him guilty only as a party, and that therefore the jury should have been instructed that if it believed him guilty only as a party, then it could consider that circumstance in determining his punishment.
This argument has again not been preserved for our review. Although appellant stated vaguely at trial that he was “challenging the constitutionality of [Article 37.071]” because “[t]here is no way to allow mitigation on behalf of the defendant, who was not the triggerman,” appellant did not request any particular instruction regarding the alleged mitigating circumstances of the offense. Nor did he press his objection to the point of an adverse ruling. Nor did appellant explain to the trial court — or to this Court — how the mitigating circumstance (if it is such) in question had relevance to his deathworthiness beyond the scope of the special issues mandated by Article 37.071(b). See Penry v. Lynaugh, 492 U.S. 302, 109 S.Ct. 2934, 106 L.Ed.2d 256 (1989).14 Point fourteen is overruled.
[232]*232Finally, in his sixteenth point of error, appellant argues that statistical studies have shown that, in Texas, the death penalty is more likely to be assessed when the victim is white (as in this case) than when the victim is a member of a racial minority. Appellant contends this disparity renders his capital sentence invalid under federal constitutional guarantees of due process and equal protection and against cruel and unusual punishment.15
It is not difficult to answer this point of error. Appellant has provided no argument or authority whatsoever with respect to due process, and the balance of his point of error was rejected in McCleskey v. Kemp, 481 U.S. 279, 107 S.Ct. 1756, 95 L.Ed.2d 262 (1987). Point sixteen is therefore overruled.
The judgment of the trial court is AFFIRMED.
