FT. MYERS, Fla. -- A 40-year-old investigation into a missing Wisconsin woman ended earlier this week when members of the Muskego Police Department arrested a cold case suspect in Ft. Myers, Florida.

John Bayerl, 78, was arrested Tuesday on a charge of 1st Degree Murder in the disappearance of his wife, Dona Mae Bayerl, who police say was 38 years old when she disappeared.

All the way back in May of 1979, John reported his wife missing and told police that she stormed out of their home after an argument, never to be seen again. Friends and family insisted Dona Mae would never leave her daughters behind, who were 7 and 4 years old at the time.

Though Dona Mae was declared dead in 1986 and the case eventually ran cold, police say they never closed the investigation, and "officers continued to be assigned to the cold case." John Bayerl continued to remain a person of interest as the case was eventually reclassified from a missing person case to a homicide.

A warrant for John's arrest was issued last Friday, February 15, and the Muskego Police Department traveled to Ft. Myers to take Bayerl into custody with assistance from the Lee County Sheriff's Department. Bayerl waived extradition and is currently in the Waukesha County Jail.

In 2017, Muskego Police shared a new age progression picture of what Dona Mae may look like at age 77.

"This woman basically vanished without any kind of trace evidence," said Detective Steve Westphal, Muskego Police.

"Apparently she had an argument with her husband at the time and she returned home after that argument and then at some point either left of something else happened to her and she was never seen from again," said Detective Westphal.

Forensic artists with the FBI lab at Quantico used photos of Dona Mae, her parents, her sister and daughter to determine what she might look like.

"I thought it was kind of cool that I got the opportunity to see what perhaps she looked like," said Jodie Jarvis, daughter.

"When I see pictures of my mom that I have I think of her as my mom, but when I see this picture of the age progression I think that's my children's grandma...."Mostly I would say that hope came along with that picture. Hope for answers, hope for closure," said Jackie Kort, daughter.

Jodie was 7 years ld and Jackie was 4 years old when their mom went missing. It's hard for them to remember many details about their mom missing.

"The police would come I would just tell them basically what I was told from my dad I think, which was that I went to bed, he heard some noises like a door slam or something like that and when I woke up she wasn't there," said Jarvis.

"The vivid things that I do remember are being very afraid and police coming into the house and I would hide," said Kort.

Not a day goes by when they don't think about their mom.

"Just imagine if you didn't know where your mother was. It's not a nice way to grow up," said Jarvis.

"The pain never goes away. The searching never goes away," said Kort.
