SIOUX FALLS - A state prison inmate who walked away from a minimum-security unit in Rapid City earlier this month is back in custody. Authorities are still looking for an inmate who failed to return to a similar unit in Sioux Falls.

State Corrections officials say 19-year-old Cody Summerside was apprehended by local authorities on Monday near Rapid City. He had left the prison on March 8 to search for a work release job and didn't return. Summerside was serving a four-year sentence on a Meade County drug charge.

Thirty-year-old Travis Thorngren went missing Monday from the minimum-security unit at the South Dakota State Penitentiary in Sioux Falls.  He had been serving a five-year sentence on a grand theft conviction in Lincoln County.
