The father of a missing 3-year-old boy says he does not know why the child and his mother were in Milwaukee, where the boy’s mother was found dead of an apparent homicide.

As CrimeOnline previously reported, Major P. Harris has been missing since at least Thursday, when his mother Mallery M. Muenzenberger was found dead in a yard in Milwaukee. Police initially believed the boy may have been with the suspect in his mother’s murder, but authorities apprehended that man on Sunday and did not find the child with him. As police were approaching the suspect at a residence in Milwaukee, he fatally shot himself.

An AMBER Alert remains active for the missing child.

Major and his mother reportedly lived in La Crosse, which is about 170 miles from Milwaukee. The boy’s father, Carlton Harris, who lives in West Virginia, told TMJ-4 that he doesn’t know why the boy and his mother were in Milwaukee. Further, multiple reports indicate that investigators are not certain when Major was last seen. There has been no official confirmation that the boy was at the home where his mother was found dead, and a police report stated that Major was last seen on October 9 in La Cross, at which time he may have been on his way to Milwaukee.

Police and volunteers have been searching for the missing boy, but so far have not located him — even after police found the suspect’s vehicle.

Harris, the boy’s father, traveled from West Virginia to join the search and meet with investigators, but told TMJ-4 that he still has many unanswered questions.

Harris also said that he had been working towards bringing Major to live with him in West Virginia. Harris and Major’s mother appeared to have had an amicable relationship, and he told TMJ-4 that “she needed help,” suggesting that she may have been struggling to care or provide for Major.

Anyone with possible information about Major’s whereabouts is urged to call the Milwaukee Police Department Sensitive Crimes Division at 414-935-7405.
