Details of Disappearance

DonaMae was last seen at her home on Fennimore Lane in Muskego, Wisconsin on May 6, 1979. Her husband, John Bayerl, stated they had an argument and she left in the family car to cool off. When she had not returned by 10:20 p.m., he went to bed.

About an hour later, he was awakened by the sound of a door slamming downstairs, and thought DonaMae had come home. When she didn't come to bed, he came downstairs to look for her and found the car in the garage and the garage door open. There was no sign of DonaMae and she has never been heard from again. John reported her missing three days later.

Ten days later, DonaMae's sister came to visit her house and found bloodstains on the wall inside the garage. There was evidence of a struggle, including items knocked over. The police, who had initially thought DonaMae left of her own accord, began to suspect foul play after this was discovered. The blood turned out to be DonaMae's type, and John said he didn't know how it got there.

DonaMae was a housewife at the time of her disappearance; her daughters were seven and four. John raised them alone after DonaMae disappeared, and remained in the Fennimore Lane residence. He is the prime suspect in his wife's disappearance, but there is no evidence to implicate him. DonaMae's case remains unsolved and foul play is suspected.
