COEUR D'ALENE, Idaho (AP) — Authorities have arrested a man in eastern Washington state they say forced a northern Idaho man to eat a fatal dose of methamphetamine.

The Spokesman-Review reports in a story on Wednesday that the Spokane County Sheriff's Department arrested 43-year-old Shaun Patrick Kelly on Friday. He's being held without bond and has agreed to be extradited to Kootenai County where he faces charges of second-degree murder, aggravated assault and unlawful possession of a firearm.

Authorities say that Kelly last August forced 22-year-old Evan Mychal Larkin at gunpoint to eat a lethal dose of meth to prove he wasn't a police informant. Larkin began foaming at the mouth and died three days later. Larkin is the grandson of Clay Larkin, who served as the Post Falls mayor for 13 years.
