First District of Texas

offense of manslaughter and (2) finding that appellant gave effective consent for the police to obtain a buccal swab to collect his DNA without a warrant. A prior panel of this Court overruled appellant’s first issue but sustained his second after concluding that the State failed to prove by clear and convincing evidence that appellant’s consent to the buccal swab was knowing and voluntary.1 The trial court’s determination as to consent resulted in the admission of DNA evidence during the punishment phase of appellant’s criminal trial that connected him to an extraneous murder. This Court found the error harmful, reversed the trial court’s judgment as to punishment only, and remanded the case to the trial court for a new punishment hearing.

The State filed a petition for discretionary review. The court of criminal appeals granted the State’s petition, vacated this Court’s judgment, and remanded the case to this Court to determine whether appellant preserved error related to the admission of the DNA evidence connecting him to the extraneous offense during the punishment phase of his criminal trial. On reconsideration of appellant’s second issue, we conclude that appellant waived error and, finding it unnecessary to readdress appellant’s first issue, affirm the trial court’s judgment. See Calhoun v.

Background

A. Appellant’s DNA Sample The factual background is detailed in our prior opinion, and we repeat only those facts that are relevant to this appeal on remand. Romero v. State, No. 01-22- 00639-CR, 2024 WL 3974425, at *1–5 (Tex. App.—Houston [1st Dist.] Aug. 29, 2024) (mem. op., not designated for publication), vacated, No. PD-1078-24, 2025 WL 925858 (Tex. Crim. App. Mar. 26, 2025) (not designated for publication).

After being arrested and given Miranda warnings,2 appellant confessed to killing Maria Marquez. Following appellant’s confession, a Houston Police Department (HPD) officer collected a buccal swab of appellant’s saliva.

2 Miranda v. Arizona, 384 U.S. 436 (1966).

Unrelated to Marquez’s death, the Pasadena Police Department (PPD) was investigating the killing of Guillermo Gonzalez. PPD eventually learned of and requested appellant’s DNA sample and compared the sample to the DNA that had been recovered in their investigation of Gonzalez’s death. The Harris County Institute of Forensic Science (HCIFS) prepared a comparison analysis of appellant’s DNA from the saliva sample and the DNA profile collected from Gonazlez’s body and the car in which Gonzalez was found. During the punishment phase of appellant’s trial, an HCIFS case management supervisor testified that the comparison analysis showed “very strong support” that appellant was a contributor to the DNA obtained from the interior handle of the driver-side door, steering wheel, and ignition of Gonzalez’s car; “moderate support” that appellant was a contributor to the DNA obtained from the back pocket of Gonzalez’s pants and left hand; and “very strong support” that appellant was a contributor to the DNA obtained from Gonzalez’s right hand and his ankles.

During the State’s closing of the punishment phase, the prosecutor argued that the evidence proved beyond a reasonable doubt that appellant had killed Gonzalez because it showed that Gonzalez and appellant had been co-workers, appellant lived in close proximity to the carwash where Gonzalez’s body was found, surveillance footage showed a man walking from the carwash toward the apartment complex where appellant lived, and appellant told his sister and brother-in-law that he had

stabbed somebody. The prosecutor then discussed the results of the DNA comparison analysis, stating: “The DNA is incredibly probative in this case, and it tells you who the killer is.” B. Objections During Trial During the guilt-innocence phase, the State offered into evidence a copy of a consent form signed by appellant in which appellant purportedly consented to the collection of his saliva. Defense counsel objected to the admission of the consent form into evidence because it was in English—appellant speaks Spanish and HPD officers interviewed him in Spanish—and it was not read to him or translated for him in Spanish. The State responded that appellant consented orally to the buccal swab and that the State was not relying solely on the written consent to prove the voluntariness of the collection. The trial court overruled appellant’s objection and admitted the written consent form into evidence.

Later that day, the State sought to admit appellant’s buccal swab into evidence. Appellant’s counsel asked to approach the bench and, outside the presence of the jury, stated that she was objecting on the grounds that appellant’s consent was not voluntary. The trial court did not entertain further argument and stated, “I already ruled it was admissible.” Appellant’s counsel then formally objected to the admission of the buccal swab in the presence of the jury “[o]n the grounds I stated earlier,” and the trial court overruled the objection.

During the punishment phase of appellant’s criminal trial, after the jury had found appellant guilty of Marquez’s murder, the State sought to introduce swabs used to collect any trace DNA evidence at the scene of Gonzalez’s death as well as swabs used to collect genetic samples from known persons of interest. Appellant’s counsel stated, “Subject to my previous objection, to State’s Exhibit 136 [the buccal swab collecting appellant’s saliva], I—other than that, I have no objection.” The trial court admitted the swabs.

After the trial court admitted the swabs, the State then sought to introduce forensic genetics reports comparing appellant’s DNA sample—obtained from the buccal swab—to the DNA samples collected at the scene of Gonzalez’s death. Because the forensic genetics reports were relevant only to prove that appellant committed an extraneous murder, the reports were never admitted during the guilt- innocence phase of the trial, which concerned Marquez’s murder, not Gonzalez’s. After the State offered the reports into evidence, appellant’s counsel stated, “I have no objections . . . except I just ask that the State remove the stickies from the reports before they go back to the jury room, if they do at all.” The trial court admitted the reports. An HCIFS case management supervisor then testified to the preparation and content of the reports without objection from appellant’s counsel.
