Jurors in Waukesha County found 79-year-old John Bayerl guilty on Wednesday after hearing closing arguments. Bayerl was arrested in Fort Myers, Florida, in February and was extradited to Waukesha, Wisconsin, to stand trial in the death of 38-year-old Dona Mae Bayerl.
WITI-TV reports John Bayerl declined to take the stand, and the defense decided not to present any of its own evidence.
Bayerl reported his wife missing on May 9, 1979. He told police she left their home in Muskego after an argument three days earlier. She was legally declared dead in 1986.
Bayerl faces a mandatory sentence of life in prison.
