Authorities are looking for a man who left Casper Re-Entry Center on Thursday and did not return as scheduled.
Scott Lee, 32, left the detention center for work at 12:45 p.m. Thursday and did not return when he was due back at 10 p.m. that night, Sgt. Aaron Shatto said.
The sheriff's department had not found Lee by Monday morning.
Lee was serving part of a two-to-four year sentence after being convicted of robbery in Clark County.
He is a five-foot 11-inch tall, 200 pound, blond-haired white man with hazel eyes, according to a Natrona County Sheriff's Office deputy
The Casper Re-Entry Center is a privately owned facility that provides rehabilitation and substance abuse treatment to inmates before they are released.
The center operates under a contract with the Wyoming Department of Corrections.
The Wyoming Board of Patrol describes the Casper Re-Entry Center and other similar facilities as providing an "alternative to incarceration or traditional probation/parole supervision."
Residents of the facility are required to hold off-site jobs and pay rent as part of their rehabilitation, according to the parole board.
The Natrona County Sheriff’s Office asked anyone with knowledge of Lee's whereabouts to call 307-235-9282.
