Jurors in Tanner Horner's murder trial viewed photos of his FedEx truck, the grim vessel prosecutors say was used to snatch 7-year-old Athena Strand from her own driveway and end her life.

On Friday, prosecutors showed the jury a series of pictures from inside the truck where Athena was murdered by Horner, 34, in Texas Nov. 30, 2022. Horner pleaded guilty to the murder and is waiting for the jury to decide if he will be sentenced to life in prison or the death penalty.

Throughout the week, prosecutors showed jurors hours of evidence as they used opening statements to paint Horner as calculating, violent and remorseless in the killing of Athena.

"First thing Tanner Horner says to Athena when he picks her up, puts her in that truck, leans down and he says, ‘Don’t scream or I’ll hurt you,’" prosecutor James Stainton told jurors in opening statements Tuesday.

"I’m going to tell you right now. One thing you’re going to hear that is something you can’t unhear is the level of fight that a 7-year-old girl has when she’s facing down a certain death."

"Guilty, your honor," Horner replied.

"Thank you. I will accept your plea," the judge said.

Authorities said Horner was delivering a package containing Barbie dolls intended as a Christmas gift for the 7-year-old when he abducted and killed her.

Her body was found less than 10 miles from the home after a massive search involving law enforcement officers, volunteers, dogs, horses and off-road vehicles.
