The trial on Wednesday morning started out with testimony from several forensic scientists from the Texas Department of Public Safety Crime Lab providing testimony about their work with the DNA evidence collected in this case. 

One of the witnesses described the process of confirming that the DNA belonged to both Horner and Athena. Another talked about collecting samples. Yet another talked about the decision to send some samples to an out-of-state lab for testing.

Tanner Horner Trial Day 6 Recap

Following a day of graphic and emotional testimony, jurors are expected to hear further details regarding forensic evidence collected from both the victim and the defendant.

On Tuesday, Jacqueline Ferrara, a former forensic analyst with the Texas Department of Public Safety, testified about DNA recovered during the investigation. Ferrara told the court that male DNA was detected on swabs from the child’s sexual assault kit, though she did not provide specific matches during that portion of her testimony.

Analysts also confirmed the presence of blood under the girl’s fingernails and male DNA on her clothing. However, Ferrara noted the limitations of forensic timing, admitting that the exact age of a stain on the clothing could not be determined.

"It is an estimate. It is not an exact, precise calculation," Ferrara said of the DNA quantification process. "But it is a very close, rough estimate of how much total human DNA is present in that sample and how much male DNA is present as well."

The proceedings took an even more somber turn Tuesday when two women took the stand to testify about alleged prior assaults by Horner. Both women alleged that Horner raped them when they were 16 years old, and he was an adult.

According to testimony, the women did not come forward to law enforcement until after Horner was arrested for Strand’s murder. One of the women is the accuser in two active sexual assault of a child cases currently pending against Horner in Tarrant County.

Horner, a former contract delivery driver, is accused of kidnapping the 7-year-old from her father’s driveway in Paradise, Texas, in November 2022. Investigators say he confessed to hitting the girl with his van and then strangling her to death to prevent her from telling her father about the accident.

Tanner Horner Trial Week 1 Recap

The first week of the punishment phase was dominated by hours of police body camera and interrogation footage. On Thursday, jurors watched video of investigators questioning Horner about the location of the girl's body. Horner, speaking as his alter ego, said he dumped the child's clothes along the highway because he "thought it was funny."

Horner previously told police he did not kill Strand, instead blaming an alter ego he called "Zero." A sergeant with the Texas Rangers testified that he obtained more information about the crime by questioning "Zero" directly. The sergeant noted that Horner would roll his eyes back before switching personalities, displaying a marked change in his physical demeanor.

The jury was also shown photos of Horner’s residence and the locations where the clothing was recovered. In another interview shown to the court, Horner asked investigators to release him from jail for one month so he could spend Christmas with his family, promising to "tell everything" if they agreed.

Athena Strand’s Death

The backstory:

Horner was charged with capital murder for the death of 7-year-old Athena Strand outside her family’s Wise County home on Nov. 30, 2022.

A contract delivery driver working for FedEx at the time, Horner was delivering what was meant to be a Christmas present for the young girl.

Horner told investigators he accidentally hit Athena with his van while delivering a package to her home. She reportedly survived, but Horner told authorities he panicked and kidnapped her, later strangling her to death.

Athena was reported missing, and eventually an Amber Alert was issued, leading to 72 hours of searching. She was found dead in Boyd, Texas, not far from her family's home.

Athena Alert

The Impact:

After Athena Strand's case, Texas Legislators passed a new bill that created a version of an Amber Alert known as the ‘Athena Alert.’

The new law allows authorities to issue an Amber Alert for a missing child that doesn’t have to meet all of the initial criteria.

Under the Athena Alert law, an Amber Alert can still go out even though authorities haven’t confirmed a missing child was kidnapped.

The alert would be able to be sent out to a 100-mile area around the disappearance and adjacent counties.

DPS emphasizes that this is not a new type of alert. All alert messages will still be referenced as an Amber Alert.
