The Tennessee Department of Correction didn't respond to multiple requests for comment to Fox News Digital.Former federal prison warden Cameron Lindsay told Fox News Digital the delay in notifying local police of an inmate escaping prison is "100% unacceptable.""Part of any correctional facilities, basic tenets of operations should include emergency plans. And one of those plans that you have for an emergency is an escape. And part of your escape plans entails notifying law enforcement, local law enforcement, state law enforcement, U.S. Marshals Service. And everybody in the community, you need to get that word out immediately. So for them to have that kind of delay raises a huge red flag," Lindsay said."And it begs the question, why, why did they delay? Because it is 100% unacceptable in the profession of corrections," he added.Lindsay said local law enforcement should have immediately been contacted once prison staff realized the inmate was unaccounted for.Retired FBI Special Agent Jonathan Gilliam told Fox News Digital the community should have been notified much sooner."That community should put out an emergency text to everyone to make sure none of their family members are missing as he could have killed or kidnapped someone after ditching the truck," Gilliam said.TBI said on Wednesday afternoon that the reward in the search for Morley is now $15,000 – $7,500 from the governor’s office, $5,000 from the U.S. Marshals and $2,500 from TBI.Morley is described as 5 feet, 11 inches tall, and 240 pounds, with brown hair and green eyes.
