Major Harris Update: 3-Year-Old Child Missing Days After Mother, Her Suspected Killer Found Dead

The search for a 3-year-old boy continued Monday in Milwaukee, days after he was reported missing and his mother was found dead.

The child, identified as Major Harris, has been missing since at least the time of his mother's death Thursday. The police had received a call Thursday morning about a dead body on 37th Street. The body of Mallery Muenzenberger, 25, of Onalaska, was first found by her mother in the latter's backyard.

Later on Saturday, the police issued an Amber Alert, and said Major was likely in danger. Major's father, Carlton Harris Jr., told NBC affiliate WTMJ of Milwaukee he did not know why the boy or his mother, who are from the La Crosse area – more than 170 miles from Milwaukee – were in the city.

During investigation, the police said the suspect in the case was 20-year-old Jaheem Clark. The suspect was found dead in the house on North 41st Street where he shot himself when the police arrived to arrest him. Investigators found Clark's SUV behind a laundromat Monday less than a mile from the house, Milwaukee Journal Sentinel reported.

Earlier, the police said Clark might have been driving a black 2008 Chevrolet Equinox. After he was found dead, the police began canvassing the area for Major "out of an abundance of caution" and as part of a multi-jurisdictional search.

The police described Major as a thin, light complexion Black child, approximately 3 feet tall and 40 pounds, with black hair in four shoulder-length zigzag braids. He has brown eyes and was last seen wearing a dark blue T-shirt with a small pocket on the left side, navy-blue basketball shorts and no shoes or socks.

Milwaukee police also briefly searched for Harris at nearby McGovern Park, while a group of community members looked for him at three separate locations. However, as of late Monday, there was no evidence about the whereabouts of the child.

Authorities urged the public to contact the Milwaukee Police Department at 414-935-7405 with any information related to the disappearance of Major. To remain anonymous, contact Crime Stoppers at (414) 224-TIPS or use the P3 Tips App, police said.

"The Milwaukee Police Department, as well as numerous local, state and federal agencies, have been actively searching for Major," the department said in a statement.
