CLAYTON -- A Danville man who escaped from a minimum-security jail in Clayton early Monday morning is back in police custody, a spokesman for the Contra Costa Sheriff's Office said.

Sheriff's Office deputies arrested 21-year-old Kohlton Kumnick of Danville just after 10 a.m. Monday morning after he walked away from the Marsh Creek Detention Facility several hours earlier, spokesman Jimmy Lee said. A Clayton resident called authorities after spotting Kumnick near Rialto Drive, about three miles from the facility, Lee said. Kumnick was captured after a brief search, he said.

Sheriff's deputies discovered that Kumnick was missing during a 3:30 a.m. head count Lee said. It was later determined that Kumnick walked away from the facility. Deputies searched the jail and surrounding areas and notified residents in the immediate area through a telephone emergency notification system. Other police agencies also were contacted, Lee said.

Kumnick was serving a 90-day sentence on a burglary charge. He was taken to the Martinez Detention Facility where he was being held on suspicion of escaping a jail.
