The incident happened Saturday, May 8, near 31st and Michigan. 

According to a criminal complaint, Devon Armour attended a funeral in Milwaukee, and afterward he drove with another man to a home near 31st and Michigan to visit with family. 

Multiple children were at the residence at the time, investigators say, including a 14-year-old, the 3-year-old victim and his 12-year-old brother.
