ST. PAUL — Anoka County sheriff’s officials are investigating the disappearance of a 22-year-old man.

The Minnesota Bureau of Criminal Apprehension issued a missing-person alert Saturday for Kevin Casserly, of Anoka.

Casserly called his mom Nov. 11 saying he had the flu and had called in sick to work. Anoka County Sheriff’s Office Detective Mike Schantzen said he was last seen the next day in the Anoka area but couldn’t give other details.

“We have no indication he is deceased,” he said Sunday. “We have no indication he is alive. We are still trying to put the pieces together as to what happened.”

The BCA said Kevin Casserly’s car was found in Anoka, which his sister Alexandra Casserly said was at a location not far from his apartment. She said police told her the keys were not in the car.

The family has organized search parties that scoured the Anoka area Saturday and another search party was being organized for Sunday, Schantzen said. The sheriff’s office took over as the lead agency Saturday at the request of the Anoka police department after they couldn’t handle all the leads from the search, Schantzen said.

The family is fearing the worst.

“It’s not a search to look for evidence,” said Alexandra Casserly. “They are looking for Kevin; it’s a body search.”

Casserly has multiple convictions, including four felonies, according to the BCA. His sister said he previously used methamphetamine but “he has been staying on the clear and narrow.”

On Nov. 12, Casserly’s mother went to his apartment to check on him, Alexandra Casserly said. His mom found his apartment door slightly open and all of his belongings intact, including his cellphone and wallet. A $20 bill was on the kitchen table.

“He left his paycheck at work and things he could pawn at home,” his sister said. “A lot of things don’t make sense.”

She said Casserly doesn’t own any weapons and “nothing right now has led us to believe he’s having a relapse.”

Casserly has a 6-year-old son and 4-year-old daughter who live with Casserly’s grandmother, Esther Chrzanak.

“They don’t know anything about (his disappearance),” Chrzanak said.

Alexandra Casserly said Kevin Casserly didn’t want his children to fall prone to his past habits, so he took them to dance and karate lessons three times a week.

“To just disappear like this … he wouldn’t do it,” she said. “He wouldn’t disappear without checking in on his kids.”
