Tanner Horner told investigators he strangled Athena Strand after hitting her with his van
The disturbing details of 7-year-old Wise County girl Athena Strand death came to light Thursday in a newly filed arrest affidavit for contracted FedEx delivery driver Tanner Horner.
According to an arrest affidavit, Horner confessed to accidentally hitting Strand with his van after delivering a package at her home in Wise County earlier this month.
Athena's mom said the package Horner delivered was a box of Barbie dolls, a Christmas gift for her daughter.
The court document also said he admitted to kidnapping and strangling the girl because he was afraid she was going to tell her father that he hit her with the van.
Authorities said Horner directed investigators to CR 4668 in Boyd, where he dumped her body in the water. The area is now marked with pink balloons, which is Strand's favorite color.
Strand was found dead on Dec. 2, two days after she was reported missing from the home.
