JEROME, Idaho (AP) — A Jerome man convicted of shooting and killing his ex-wife more than 30 years ago has been released from prison.

KTVB-TV reports  that 55-year-old Jaimi Charboneau walked out of Jerome County Jail Monday night after posting $20,000 bond. Fifth District Judge Robert J. Elgee vacated Charboneau's conviction and sentence after determining the state hid significant evidence. Charboneau was convicted of murder in 1985 in the killing of Marilyn Arbaugh, his ex-wife, in Jerome County.

He was sentenced to death but was later resentenced to life in prison. He says the shooting was in self-defense. It's not clear when the Idaho Supreme Court will rule on the appeal.
