Main circumstances: McManus was last seen by members of his family in South Milwaukee on May 7, 2023.

Kevin McManus Disappears From South Milwaukee

Kevin Peter McManus was last physically seen by his family in South Milwaukee on May 7, 2023. Publicly available descriptions identify him as a white male who was approximately 6 feet 1 inch tall and weighed about 225 pounds. He had blue eyes and blond or strawberry-blond hair. FOX6 reported that his hair was very short around the time he disappeared. No description of the clothing he was wearing when last seen has been publicly established.

Although May 7 is consistently reported as the date McManus was last seen, Wisconsin Missing Persons Advocacy reports an important additional detail: McManus reportedly had contact with his family on May 15, eight days after the last reported in-person sighting.

That distinction means May 7 should be treated as the reported last sighting, while May 15 represents the later reported family contact.

Family Became Concerned After Communication Stopped

One of the few details publicly released about the circumstances involves McManus’s relationship with his family. According to Wisconsin Missing Persons Advocacy, it was unusual for him to go for an extended period without communicating with his mother.

Exactly what occurred after his reported May 15 contact has not been publicly established in the sources reviewed. Public reporting has not identified a vehicle connected to his disappearance, and FOX6 reported in August 2023 that police had not provided a vehicle description.

There also has been little publicly released information concerning McManus’s movements immediately before or after his disappearance.

Police Publicly Ask for Help

On August 30, 2023, both FOX6 News Milwaukee and CBS 58 reported that the South Milwaukee Police Department was seeking the public’s help locating McManus.

CBS 58 described him as 43 years old, approximately 6 feet 1 inch tall and 225 pounds, with blonde hair and blue eyes. The department asked anyone possessing information concerning his whereabouts to contact South Milwaukee police.

McManus’s case was entered into NamUs in September 2023 and assigned MP108016.

What Is Known About the Investigation?

Relatively little investigative information has been made public.

The publicly available sources reviewed do not identify a named suspect, publicly establish that a crime occurred, or state that McManus’s disappearance is being investigated as a homicide. There is likewise no reliable public information in the reviewed sources establishing that remains belonging to McManus have been recovered.

Because of the limited official information, theories circulated through online forums and social media should not be treated as established facts.

A Websleuths discussion about McManus was created in October 2024. Participants have discussed possible areas that might warrant searching and offered personal theories about what could have happened. Those comments are useful for documenting continued public interest in the case, but they are speculation rather than findings announced by investigators.
