BOWLING GREEN, Ky. (WBKO) -- UPDATE: Escaped Warren County Jail inmate Benjamin Pedigo is now back in custody in Tennessee.
He had been missing since February 10, when he got away while taking out trash with other inmates.
Kentucky State Police says he will be extradited back to Kentucky.
According to Jailer Stephen Harmon, the inmates were under supervision.
"The staff called just after 9:15 p.m. (Sunday night) when the inmate ran off from the side of the building where we take trash out," said Harmon.
"Everybody's doing their absolute best to work together to find him," said Harmon on Monday.
Throughout Sunday night and into Monday morning, various local law enforcement agencies, Kentucky State Police, and jail staff including Jailer Harmon went knocking on doors looking for Pedigo.
Through the cold and the rain, officials are continuing the investigation late into Monday afternoon, as Pedigo is still on the run.
According to Kentucky State Police, Pedigo has been entered into a nation-wide database as an escapee.
Jailer Harmon said Pedigo was sentenced just last month to four years behind bars. The jail website lists his charges, which include drug offenses and fleeing and evading police.
"Mr. Pedigo was housed in the Class D building which his classification by the state allowed," explained Harmon.
With this classification, Pedigo was also allowed to work outside of the building under supervision.
"I know that's a concern for the public but no violations were made there," said Harmon. "The deputy did exactly what he was supposed to do. When [Pedigo] ran off he notified help immediately, contacted state police, and started our internal plan."
While the search continues, Harmon says the jail is reviewing its policies.
"Certainly now we'll look at ways to either have more help when they're outside the building or use some restraints or we'll look into those policies and see what we can do to improve that."
State Police say once Pedigo is found, he could face an escape 2nd degree charge, which is punishable by up to one year in prison.
If you know anything about where Pedigo might be, you're asked to call 911 or Kentucky State Police at 270-782-2010.
