A former FedEx delivery driver who pleaded guilty to killing a 7-year-old girl in Texas was sentenced to death Tuesday.

Tanner Horner was sentenced to death by a Tarrant County jury Tuesday afternoon for murdering 7-year-old Athena Strand.

The defense was hoping for life in prison without parole based on claims that Horner was not a danger to society and his upbringing and autism diagnosis were mitigating factors in the crime.
