Killer FedEx driver Tanner Horner claimed to police that 7-year-old Athena Strand was dead when he stuffed her in his truck, chilling bodycam video shows.

On Wednesday, Horner’s murder trial was shown video of the confessed killer callously claiming that he “tossed” her body into the woods after hitting her with his vehicle near her house in Lake Worth, Texas.

In the video, Horner replies, “I can show you,” when he is asked where Athena is during his arrest on Dec. 2, 2022, NBC 5 reported.

“Is she alive?” an officer asks Horner, who says, “She wasn’t alive when I put her in the truck.”

Texas Ranger Job Espinoza told the jury they believe that was a lie, and that Horner strangled the girl when she said she would tell her father after he bumped into her in his delivery van.

Authorities said Horner strangled Athena after unsuccessfully trying to break her neck.

Little Athena can be seen alive and kneeling in the FedEx truck in a devastating photo shown in court Tuesday.

In the bodycam video, Horner is seen walking through a wooded area, repeatedly saying that he is sure Athena’s body is there.

At one point, he tells officers they’re going too far and that he “kind of tossed her in.”

Ranger Espinoza later told the jury on Wednesday that Athena wasn’t there, and that her body was in an area of the Trinity River called BoBo Crossing nine miles away.

Horner’s defense team has said he suffers from mental illness and lead poisoning, as they look to have him avoid the death penalty and face life in prison without parole instead.

On Tuesday, he pleaded guilty to capital murder and aggravated kidnapping during his trial in Tarrant County, Texas.

During his first police interview, Horner appeared calm, laid back, and cooperative as he answered deputies’ questions about little Athena.

“He wasn’t worked up. He had a cool, calm demeanor, cooperated, spoke, was articulate, joked around, made jokes at times, made jokes inappropriately at times,” Espinoza’s brother, Job, also a Texas ranger, told the jury Wednesday.

Athena’s body was found two days after she was reported missing from her family’s property in Paradise, Texas.

Horner’s DNA was found under Athena’s fingernails, indicating she bravely tried to fight off her attacker.

There is also evidence that the sicko sexually assaulted Athena either before or after he killed her.

Horner’s DNA was found “in places where you shouldn’t find DNA on a 7-year-old girl,” Wise County District Attorney James Stainton told the jury on Tuesday.

The jury is set to be shown harrowing footage of Athena’s final moments at the hands of Horner.

“Don’t scream or I’ll hurt you,” Horner told Athena after picking her up and putting her in his truck, Stainton told the trial on Tuesday.

“You are going to hear what a 250-pound man can do to a 67-pound child. And when I say it’s horrible, I mean it,” he said.
