IN THE TENTH COURT OF APPEALS
No. 10-23-00044-CR
STEVENSON RANDOLPH CARL, Appellant v.
THE STATE OF TEXAS, Appellee
From the 19th District Court McLennan County, Texas Trial Court No. 2019-2197-C1
MEMORANDUM OPINION
Appellant, Stevenson Randolph Carl, was charged by indictment with five counts
of possession of child pornography. See TEX. PENAL CODE ANN. § 43.26. Carl filed a
motion to suppress, arguing that items seized during a search of his residence should be
suppressed because the acquisition of Carl’s subscriber information by use of
“investigative software” to determine Carl’s IP address and an administrative subpoena constituted a violation of his rights under the Fourth Amendment of the United States
Constitution and article I, section 9 of the Texas Constitution. See U.S. CONST. amend. IV;
see also TEX. CONST. art. I, § 9. After a hearing, the trial court denied Carl’s motion to
suppress.
After the denial of his motion to suppress, Carl entered an open plea of guilty to
the charged offenses without any recommendation from the State. The trial court
accepted Carl’s guilty plea, found him guilty, and assessed punishment at ten years in
prison for each of the first four counts and two years in prison for the fifth count. The
trial court ordered the first four counts to run concurrently and the fifth count to run
consecutive to the first four counts. This appeal followed.
In his sole issue on appeal, Carl contends that the trial court abused its discretion
by denying his motion to suppress. We affirm.
Standard of Review
We review a trial court’s ruling on a motion to suppress evidence under a
bifurcated standard of review. Amador v. State, 221 S.W.3d 666, 673 (Tex. Crim. App.
2007). In reviewing the trial court’s decision, we do not engage in our own factual review.
Romero v. State, 800 S.W.2d 539, 543 (Tex. Crim. App. 1990). The trial judge is the sole
trier of fact and judge of the credibility of the witnesses and the weight to be given their
testimony. Wiede v. State, 214 S.W.3d 17, 24-25 (Tex. Crim. App. 2007). Therefore, we give
almost total deference to the trial court’s rulings on (1) questions of historical fact, even if
Carl v. State Page 2 the trial court’s determination of those facts was not based on an evaluation of credibility
and demeanor; and (2) application-of-law-to-fact questions that turn on an evaluation of
credibility and demeanor. Amador, 221 S.W.3d at 673; see Montanez v. State, 195 S.W.3d
101, 108-09 (Tex. Crim. App. 2006). But we review de novo the trial court’s determination
of the law and its application of law to facts that do not turn upon an evaluation of
credibility and demeanor. Amador, 221 S.W.3d at 673.
When reviewing the trial court’s ruling on a motion to suppress, we must view the
evidence in the light most favorable to the trial court’s ruling. Wiede, 214 S.W.3d at 24;
see State v. Kelly, 204 S.W.3d 808, 818 (Tex. Crim. App. 2006). When the trial court makes
explicit fact findings, we determine whether the evidence, when viewed in the light most
favorable to the trial court’s ruling, supports those fact findings. Kelly, 204 S.W.3d at 818-
19. We then review the trial court’s legal ruling de novo, unless the trial court made
explicit findings of fact supported by the record that are dispositive of the legal issue. Id.
at 819.
Analysis
In his sole issue on appeal, Carl contends that child pornography seized from his
residence based on the search warrant should have been suppressed because the search
for Carl’s subscriber information required a search warrant, similar to the collection of
cell-site location information (“CSLI”), and because a subpoena cannot be a substitute for
a search warrant. We disagree.
Carl v. State Page 3 APPLICABLE LAW
The Fourth Amendment to the United States Constitution and article I, section 9
of the Texas Constitution protect against unreasonable searches and seizures by
government officials. See U.S. CONST. amend. IV; TEX. CONST. art. I, § 9; see Wiede, 214
S.W.3d at 24; Hunter v. State, 92 S.W.3d 596, 601 (Tex. App.—Waco 2002, pet. ref’d).
Generally, officers must obtain a warrant before they can examine an individual’s private
property. See Katz v. United States, 389 U.S. 347, 357, 88 S. Ct. 507, 514, 19 L. Ed. 2d 576
(1967); see also State v. Rodriguez, 529 S.W.3d 81, 87 (Tex. App.—Eastland 2015), aff’d, 521
S.W.3d 1 (Tex. Crim. App. 2017). In the past, a violation of the right against unreasonable
search and seizure was a matter of trespass, but in Katz, the United States Supreme Court
stated that individuals may be protected from unreasonable searches and seizures if they
demonstrate an expectation of privacy. Carpenter v. United States, 138 S. Ct. 2206, 2213,
201 L. Ed. 2d 507 (2018); United States v. Jones, 565 U.S. 400, 407-08, 132 S. Ct. 945, 950-51,
181 L. Ed. 2d 911 (2012); Katz, 389 U.S. at 353, 88 S. Ct., at 512; Sims v. State, 569 S.W.3d
634, 643 (Tex. Crim. App. 2019). Whether a legitimate expectation of privacy exists is a
question of law. Villarreal v. State, 935 S.W.2d 134, 138 n.5 (Tex. Crim. App. 1996). The
defendant bears the burden of proving facts establishing a legitimate expectation of
privacy. Id. at 138. “To carry this burden, the accused must normally prove: (1) that by
his conduct, he exhibited an actual subjective expectation of privacy, i.e., a genuine
intention to preserve something as private; and (2) that circumstances existed under
Carl v. State Page 4 which society was prepared to recognize his subjective expectation as reasonable.” Id.
(citing Smith v. Maryland, 442 U.S. 735, 740, 99 S. Ct. 2577, 2580, 61 L. Ed. 220 (1979)); see
Sims, 569 S.W.3d at 643; see also Rodriguez, 529 S.W.3d at 87.
DISCUSSION
On appeal, Carl contends that he has a privacy interest in his subscriber
information such that a search warrant was required to obtain this information. Texas
courts and courts throughout the country have held that an individual does not have a
reasonable expectation of privacy in subscriber information provided to an Internet
Service Provider. See Russo v. State, 228 S.W.3d 779, 802 (Tex. App.—Austin 2007, pet.
ref’d) (citing numerous cases from the federal system and other states holding that there
is no Fourth Amendment protection against the disclosure of subscriber information by
Internet Service Providers because there is no reasonable expectation of privacy in
subscriber information provided to Internet Service Providers); see also Chavis v. State,
2011 Tex. App. LEXIS 6838, at *14 (Tex. App.—El Paso Aug. 26, 2011, pet. ref’d); accord

Sims, 569 S.W.3d at 643; see also Rodriguez, 529 S.W.3d at 87.
DISCUSSION
On appeal, Carl contends that he has a privacy interest in his subscriber
information such that a search warrant was required to obtain this information. Texas
courts and courts throughout the country have held that an individual does not have a
reasonable expectation of privacy in subscriber information provided to an Internet
Service Provider. See Russo v. State, 228 S.W.3d 779, 802 (Tex. App.—Austin 2007, pet.
ref’d) (citing numerous cases from the federal system and other states holding that there
is no Fourth Amendment protection against the disclosure of subscriber information by
Internet Service Providers because there is no reasonable expectation of privacy in
subscriber information provided to Internet Service Providers); see also Chavis v. State,
2011 Tex. App. LEXIS 6838, at *14 (Tex. App.—El Paso Aug. 26, 2011, pet. ref’d); accord
United States v. Bynum, 604 F.3d 161, 164 (4th Cir. 2010) (noting that every federal court
that has addressed the issue has held that there is no reasonable expectation of privacy in
subscriber information), cert. denied, 130 S. Ct. 3442, 177 L. Ed. 347 (2010); Guest v. Leis,
255 F.3d 325, 336 (6th Cir. 2001) (noting that “computer users do not have a legitimate
expectation in their subscriber information because they have conveyed it to another
person—the system operator”); United States v. Hambrick, 55 F. Supp. 504, 507-09 (W.D.
Carl v. State Page 5 Va. 1999) (holding that an individual has no reasonable expectation of privacy in his
name, address, social security number, credit card number, screen name, and proof of
Internet connection obtained from an Internet Service Provider because “a person has no
legitimate expectation of privacy in information he voluntarily turns over to third
parties”).
Moreover, Carl does not direct us to any authority specifically holding that he has
a privacy interest in his subscriber information such that a search warrant was required
to obtain this information. Rather, Carl attempts to analogize the procurement of his
subscriber information to CSLI. See generally Carpenter, 138 S. Ct. at 2206. However, we
note that the Court of Criminal Appeals has emphasized that a recognized expectation of
privacy in CSLI records must be decided on a case-by-case basis and that short-term
surveillance of CSLI does not violate a person’s legitimate expectation of privacy. See
Sims, 569 S.W.3d at 645-46. In addition, we also note that Carl’s conduct did not exhibit
an actual expectation of privacy.
In its findings of fact and conclusions of law, the trial court noted the following:
Sgt. Gary Marquis, with the Attorney General’s Child Exploitation Unit, began an investigation with peer-to-peer cases on BitTorrent network. Peer-to-peer is a network which shares files from one device to another device if the devices have the same software. One of the software types is BitTorrent, that allows file sharing, is an open software program that is available to anyone who chooses to download it on their electronic device. BitTorrent is an open software program which means there is no reasonable expectation of privacy.
Carl v. State Page 6 Sgt. Marquis, using a law enforcement program authorized by statute, opened his software to begin looking for “info hashes.” The software looks for the info hashes which denotes files of interest that are known to contain child pornography. The software indicated a device contained the info hashes which indicated said device contained child pornography. The law enforcement software further identifies the IP address of the device that is openly sharing information which further means there is no reasonable expectation of privacy.
The IP address provider is found by using a public database; “www.what’smyIPaddress.com.[“] Thereafter, after additional surveillance, investigation, and the issuance of an administrative subpoena authorized by the Government Code Section 422.002 to obtain subscriber information, Sgt. Marquis obtained the address of the identified IP address user.
Thereafter, a Search Warrant was issued based upon probable cause that the defendant lived at the target address and used a device with the identified IP address which share the info hash that was consistent with known child pornography.
None of the technology used by Sergeant Marquis intruded on Carl’s reasonable
expectation of privacy. Indeed, the fact that Sergeant Marquis used open software that
allows peer-to-peer file sharing and a law-enforcement program authorized by statute to
determine the IP address of the device Carl used to download child pornography
lessened any reasonable expectation of privacy Carl has in the IP address. See Brackens v.
State, 312 S.W.3d 831, 837 (Tex. App.—Houston [1st Dist.] 2009, pet ref’d) (“[A] private
party search can destroy an individual’s reasonable expectation of privacy if the
individual’s conduct or activity or the circumstances of the situation significantly lessen
the defendant’s reasonable expectation of privacy by creating a reasonably foreseeable
risk of intrusion by private parties. In such a situation, any subsequent law enforcement Carl v. State Page 7 search must be limited in scope to the private party’s legitimate search.” (citing United
States v. Barth, 26 F. Supp. 2d 929, 937 (W.D. Tex. 1998)).
Carl also complains about Sergeant Marquis’s use of section 422.033 of the Texas
Government Code to obtain the issuance of an administrative subpoena to gather further
identifying information. Carl emphasizes that law enforcement must obtain a search
warrant for the information gleaned from the section 422.033 administrative subpoena
because he has a privacy interest in his subscriber information. As we concluded earlier,
Carl did not demonstrate that he has a privacy interest in his subscriber information.
Therefore, a search warrant was not required to obtain his subscriber information.
Furthermore, the administrative subpoena procured by Sergeant Marquis is authorized
by statute, and Carl has not cited any authority holding that section 422.033 is invalid or
unconstitutional. See TEX. GOV’T CODE ANN. § 422.033(a) (“The attorney general shall
assist persons authorized under this section in obtaining administrative subpoenas to
investigate and prosecute offenses that involve the Internet-based sexual exploitation of
a minor.”); see id. § 422.033(b) (noting that an administrative subpoena may issue to
require the production of records and documents if (1) “the subpoena relates to an
investigation of an offense that involves the sexual exploitation of a minor”; and (2) “there
is reasonable cause to believe that an Internet or electronic service account provided
through an electronic communication service or remote computing service has been used
in the sexual exploitation or attempted sexual exploitation of the minor”); see also Robinson
Carl v. State Page 8 v. State, No. 09-21-00350-CR, 2022 Tex. App. LEXIS 9076, at **15-16 (Tex. App.—
Beaumont Dec. 14, 2022, no pet.) (mem. op., not designated for publication) (“We
conclude that the trial court did not err by straying from the literal language and
considering extra-textual factors such as legislative history, intent, and purpose;
determining that section 422.033 applied when Robinson believed the undercover officer
was a minor; and finding that section 422.033 allowed the undercover officer to use
administrative subpoenas to recover records from KIK and Grande Communications to
investigate and prosecute an offense that involved the internet-based sexual exploitation
of a minor.”).
Therefore, based on the foregoing, we cannot conclude that the trial court abused
its discretion by denying Carl’s motion to suppress. Accordingly, we overrule his sole
issue on appeal.
Conclusion
We affirm the judgments of the trial court.
