TUCSON - The Tucson Wildlife Center says the only surviving bat from the mass bat killing earlier this month died, Thursday night.
The 33 bats were found under Benson Highway Bridge near the Sheriff's Department.
Twenty bats were already dead and 12 had to be euthanized because of their multiple broken bones.
There is still a $1000 reward for any information leading to an arrest.
