Athena Strand's murderer's last days on earth will be full of "suffering." As we previously reported, Tanner Horner was sentenced to death after murdering and assaulting the 7-year-old girl back in 2022. Now, the former FedEx driver is staying in one of the most brutal prisons in the country while awaiting death by lethal injection. According to Radar Online earlier this month, Horner was sent to the Polunsky Unit, a specialized prison outside of Houston for death row inmates known as the "Death Watch" for its rough conditions.
