PENDLETON, Ind. | A 44-year-old Gary man serving a murder sentence has been caught after attempting to escape a maximum-security prison here by scaling a prison wall, authorities said.

Larry R. Fleming was discovered outside a housing unit early Friday attempting to climb the building, Pendleton Correctional Facility Superintendent Brett Mize said.

Guards were alerted around 4:30 a.m. when Fleming was discovered to be missing from his cell.

Fleming is serving a 60-year sentence for killing 22-year-old Dwayne Henderson, of East Chicago, in May 1989 at an Amoco service station on Columbia Avenue in Hammond. He was convicted in April 1990 and is scheduled to be released in 2023.

Fleming, whose address at the time of the crime was listed as 5619 W. 24th Ave. in Gary's Black Oak neighborhood, will face prison disciplinary charges, and the Indiana State Police and the Madison County prosecutor's office will investigate possible criminal charges.
