FedEx Driver Tanner Horner Sang “Jingle Bell Rock” While 7-Year-Old Athena Strand Screamed in Pain, Chilling Trial Audio Reveals.

In one of the most disturbing moments of an already heartbreaking trial, jurors in Tarrant County, Texas, listened in tears this week as audio from inside Tanner Horner’s FedEx delivery truck captured the final moments of 7-year-old Athena Strand.

The recording, played during the sentencing phase after Horner pleaded guilty to capital murder on April 7, 2026, shows the contrast between festive Christmas music and unimaginable cruelty. Approximately 30 minutes into the audio, the radio begins playing the holiday classic “Jingle Bell Rock.” As the upbeat song fills the cab, Athena can be heard screaming in pain after Horner slammed her hard onto the floor of the truck.

Instead of showing any mercy, Horner reportedly sang along to the song while the little girl cried out. When Athena’s screams continued, he yelled at her to “shut up” and threatened to hurt her more if she didn’t stop.

The audio is part of more than an hour of video and sound evidence from inside the truck on November 30, 2022 — the day Horner kidnapped Athena from her Wise County home while delivering a package. Surveillance footage showed the 7-year-old walking just a few feet behind Horner before he picked her up and placed her in the back of the vehicle.

Athena repeatedly asked Horner if he was a kidnapper and begged to go home to her mother. The audio captures her fear, pain, and desperate pleas as the attack continued. Horner later confessed to beating and strangling the child. Her body was found in the Trinity River days later.

Jurors were visibly distraught as the evidence played. Some sobbed openly. The judge had warned everyone in the courtroom beforehand that the material was extremely graphic and offered anyone who felt they could not handle it the chance to leave.

Horner, now 34 (he was 31 at the time of the crime in late 2022), has already admitted guilt. The current trial phase is focused solely on whether he should receive the death penalty or life in prison without parole.

The chilling detail that Horner sang along to a joyful Christmas song while a terrified child screamed has shocked the public and further devastated Athena’s family. Her mother has spoken emotionally in court, asking the one question that haunts every parent: why?

This case has drawn national attention not only for the brutality of the crime but for the cold, almost casual way Horner continued driving and even sang while committing the murder. Prosecutors argue the audio demonstrates a complete lack of remorse and a level of cruelty that justifies the ultimate punishment.

Defence attorneys are expected to present mitigating factors, but the raw evidence from the truck’s own recording system has left little room for sympathy in the eyes of many observers.

Athena Strand was a bright, loving little girl whose life was stolen in the back of a delivery truck while a Christmas song played. The fact that her killer sang along as she suffered has made the crime feel even more monstrous.

As the jury deliberates Horner’s fate, the haunting audio serves as a permanent, devastating record of Athena’s final moments — a little girl crying for her mother while “Jingle Bell Rock” played on the radio and her murderer sang.

No sentence can bring Athena back. But for her family and everyone who has followed this tragic case, the hope is that justice will be as uncompromising as the horror captured on that recording.
