86-year-old guilty of killing wife in Wisconsin in 1975

STURGEON BAY, Wis. (AP) — A jury in Door County on Friday found an 86-year-old man guilty of killing his wife and disposing of her body more than four decades ago.

Jurors returned guilty verdicts on charges of first-degree murder and disinterment of the dead against Richard Pierce, who has maintained his innocence.

Carol Jean Pierce has not been seen since Sept. 5, 1975 and her remains have never been found.

Investigators say Richard Pierce moved to Cheboygan, Michigan shortly after his wife disappeared.

A cold case review team in 2018 concluded there was enough evidence to show Pierce was set to gain from his wife's disappearance.
