The man who police believe killed the boy's mother died by suicide as officers closed in on him, say authorities. On Thursday, Milwaukee police began searching for Major P. Harris, 3, who disappeared after his mother, Mallery Muenzenberger, 25, was found dead in the backyard of a Milwaukee home, the Milwaukee Police Department said in a statement. The boy was nowhere to be found after his mother's killing, say police. Police believe a suspect in the murder, Jaheem Clark, 20, may have taken the child, according to the Amber Alert issued for the boy. On Sunday at about 4:01 p.m., Clark died by an "apparent self-inflicted gunshot wound" at a home on the 5400 block of North 41st St. as officers approached it," authorities have said. But police were unable to find the boy after Clark's death, according to the Amber Alert. It's unclear how Clark knew Muenzenberger or what their relationship was.
