BOLINGBROOK, Ill. (AP) — Former police Sgt. Drew Peterson turned himself in Wednesday on a weapons charge unrelated to the disappearance of his wife, a high-profile case in which he has been named as a suspect.

Peterson turned himself in at the Bolingbrook Police Department, where he once worked, and was taken to the Will County jail. An adult son posted 10 percent of a $75,000 bond to secure his release pending trial, Peterson attorney Joel Brodsky said.

Peterson left jail without commenting.
