ALAN WILLIAM NULL, Appellant v.

THE STATE OF TEXAS

ON STATE’S PETITION FOR DISCRETIONARY REVIEW FROM THE FOURTEENTH COURT OF APPEALS HARRIS COUNTY

HERVEY, J., delivered the opinion of the court in which RICHARDSON, NEWELL, WALKER, SLAUGHTER, and MCCLURE, JJ., joined. YEARY, J., filed a concurring opinion. KELLER, P.J., and KEEL, J., concurred.

OPINION

Appellant, William Alan Null, was convicted of second-degree felony sexual assault. A DNA analyst testified at punishment that Appellant had been linked to a previous sexual assault. The analyst reached that conclusion by comparing Appellant’s profile, which she developed, to profiles an analyst at a third-party laboratory developed. Appellant objected under Rule 702 of the Texas Rules of Evidence. He argued that the analyst’s testimony was unreliable because she had no personal knowledge about the third-party laboratory or its data. The trial court overruled Appellant’s objection, and the jury convicted him and sentenced him to 60 years’ confinement. Appellant appealed, and the court of appeals ordered a new punishment trial. We will reverse the judgment of the court of appeals and affirm the judgment of the trial court.

I. BACKGROUND

A. Incident & Guilt Phase In the early morning hours one Thursday in September 2011, sixteen-year-old C.A. returned home dirty, wearing someone else’s clothes, and wrapped in someone else’s blanket. She told her mother that she had been raped. C.A. told the sexual assault nurse examiner that a man asked her if she needed a ride when she was returning home after jogging. She said that she got into his car, and he drove to a field and asked her for oral sex. When she refused, he slapped her, pushed the seat down, and got on top of her: “He took out a switchblade and he tried to cut my clothes open. Finally[,] I could not fight it anymore. He said he was going to kill me. He had sex with me.” C.A. told the nurse examiner that Appellant raped her, then kicked her out of the car, and she walked home.

At trial, C.A. testified that she skipped school the day of the incident because she did not want to see a boy. Instead, she stayed home and drank her mother’s alcohol with her friend, Mita. According to C.A., after the pair drank for a while, C.A. missed her shift at a local Goodwill, and Mita drove them to her apartment. When they arrived, C.A. said that she laid down because her stomach hurt. When she woke up, C.A. left the apartment and walked home. The next thing she remembered was waking up in a stranger’s car. She said that she felt like she was being pushed down and that she was trying to push something off her. She remembered breathing hard and hearing someone else breathing. She blacked out again and woke up in the hospital.

Janie Escamilla, C.A.’s mother, testified that she returned home to find two half-

empty liquor bottles on the counter and the bathroom smelling like someone had been sick. No one else was home. She said that she waited for C.A. for a while before driving to Goodwill to look for her. Escamilla said that C.A. arrived home at about 5:00 a.m. and

seemed “out of it.” She also said that her eyes were “glazed,” 1 her hair and makeup were 0F

messed up, she was barefoot, and she was dirty. When Escamilla began questioning her, she said that C.A. started to cry and said she had been raped.

Appellant became a suspect in 2013. 2 Police obtained a voluntary DNA sample, 1F

and Michael Donley, an analyst with the Harris County Institute of Forensic Science, developed a DNA profile and compared it to profiles developed from items in the SANE kit. His conclusions showed it was almost certain that it was Appellant’s DNA on the items in the SANE kit. Donley testified about his conclusions, and the jury convicted Appellant.

1 Toxicology testing showed that C.A.’s blood contained marijuana metabolites and alprazolam, commonly sold as Xanax, although she said that she had never taken it.

2 The record does not show how Appellant became a suspect.

B. Punishment

i. Catherine Bunch

Most of the punishment evidence was about an earlier victim, Catherine Bunch, and DNA comparisons linking Appellant to her sexual assault. Bunch told a detective that she was out walking one day when a man in an SUV asked her if she wanted a ride. She said that she got into his SUV and that he drove to a dumpster and offered her money for sex. According to Bunch, when she refused, he locked the doors and said: “Now you have no choice” before climbing on top of her and raping her. Bunch reported the rape

and was examined by a sexual assault nurse examiner. Years later, 3 portions of the Bunch 2F

SANE kit were sent to Bode Technologies, a third-party forensic laboratory. An analyst developed DNA profiles from sperm- and epithelial-fractions, authored a report, then returned the evidence to HFSC.

ii. Mary Symonds

Mary Symonds, who worked for the Houston Forensic Science Center (HFSC), 4 3F

was the testifying DNA analyst. She compared Appellant’s DNA profile to the profiles developed at Bode Technologies. Before she testified, Appellant objected, citing the Confrontation Clause and Rule 702 of the Texas Rules of Evidence. Appellant filed written objections, arguing Symonds’ testimony would be unreliable under Rule 702

3 Bunch was assaulted in October 2010. The case became inactive because police were unable to locate her. In 2017, a new detective assigned to the case was able to contact Bunch and developed Appellant as a suspect.

because she knew nothing about Bode Technologies or the technicians and analyst who worked the case. The trial court overruled Appellant’s objections but let them run.

Symonds’ testimony can be broken down into four parts: (1) how HFSC processes its own DNA cases, (2) HFSC’s protocol when using data from third-party forensic laboratories, (3) Symonds’ knowledge about Bode Technologies, and (4) conclusions she drew based on her comparisons.

a. HFSC’s Four-Step Process Symonds testified that her laboratory uses a four-step process. First, a technician attempts to extract genetic material from evidence, such as a vaginal swab or a stain on clothes. Second, the material is quantified. This involves determining whether DNA is present, and if so, isolating it. It also involves determining how much DNA was collected and its source. For example, there might be no DNA present, or it might not be from a human (e.g., another animal or bacteria). Third, certain unique repeating sequences on chromosomes called short-tandem repeats (STRs) are tagged with fluorescent markers, and billions of copies of the tagged STRs are made. Fourth, the material is processed using a capillary electrophoresis machine, which produces a graph called an electropherogram. The electropherogram shows different colors and peaks and valleys, which an analyst can possibly use to draw conclusions. For instance, an analyst might conclude that the sample is a mixture of DNA and develop a profile or profiles. On the other hand, an analyst might be unable to develop any profiles, or at least, ones suitable for comparison purposes. Analysts can also sometimes produce statistics using the Random Match Probability (RMP), Combined Probability of Inclusion/Exclusion

(CPI/CPE), or likelihood ratio (LR) methodologies. See Ex parte Napper, 322 S.W.3d 202, 223 (Tex. Crim. App. 2010) (RMP); Skinner v. State, 484 S.W.3d 434, 439 n.7 (Tex. Crim. App. 2016) (CPI/CPE); Haggard v. State, 612 S.W.3d 318, 323 n.8 (Tex. Crim. App. 2020) (LR).

b. HFSC’s Protocol for Third-Party Forensic Laboratories Symonds testified that the laboratory has a protocol when HFSC uses data generated by another laboratory to make sure that the third-party laboratory correctly performed the four-step process:
