Kentucky State Police say they are conducting a ground and air search for three inmates who escaped from a southern Indiana prison after a truck stolen a few miles from the prison was found abandoned in Kentucky.

Lt. Chad White with the Kentucky State Police Post 5 in Campbellsburg said Sunday evening there had not been any confirmed sightings of the inmates.

White says in addition to searching from the air, police are conducting road checks.

The 1989 Ford F-250 was found along Interstate 71 northbound in Carroll County, about 30 miles south of Cincinnati. Earlier in the day, Indiana State Police said that truck was apparently stolen from the town of St. Croix, just a few miles from the Branchville Correctional Facility. The three inmates from the prison escaped Friday.
