Wis. (WLAX/WEUX) – The missing La Crosse County three-year-old boy who was the subject of an ongoing amber alert is dead.

The Milwaukee police department late this afternoon said Major Harris’ body was found on the western side of Milwaukee.

Police officers earlier said they made several arrests in the murder of his mother — who was 25 and from Onalaska.

Mallery Muenzenberger was found dead from multiple gunshot wounds on Milwaukee’s north side last Thursday. Major Harris’ amber alert was issued Saturday.

Police believe Muenzenberger and Major Harris arrived in Milwaukee around October ninth.

Arrests in Harris’ death have not yet been made.
