BOISE, Idaho (AP) — A former prison guard at the Idaho State Correctional Institution has been charged with two felonies because prosecutors say he had sex with an inmate. The Idaho Department of Correction announced the arrest of Roberto Guiller Escobedo on Friday.

Escobedo worked at the prison south of Boise from June 2010 to Jan. 23, 2013. He was arrested after the department's Office of Professional Standards launched an investigation and contacted the Ada County Sheriff's Office. According to court records, Escobedo has not yet entered a plea to two counts of felony sexual conduct with an inmate.

If convicted he faces up to life in prison. Department of Correction spokesman Jeff Ray said in a prepared statement that the department won't comment further because it is a personnel matter.
