A family argument in Milwaukee on the evening of May 23, 2016, ended in a fatal shooting. Robert Thomas, 45, was found in a field behind a residence near 24th Place and Burleigh Street after police were called about a shooting at about 7:30 p.m. He had sustained a gunshot wound to the face and was pronounced dead at the scene.

The dispute began when Thomas was asked to shut a door and escalated into a physical fight. According to the criminal complaint, Perry Wallace, 27 and Thomas’s nephew, admitted to punching Thomas, throwing bricks at him and striking him with a metal pole before retrieving a shotgun, pointing it at Thomas’s face and firing. Officers arrested Wallace near the scene and recovered a firearm. Family members said both men lived together in a basement and both had schizophrenia; they also reported that Thomas commonly wore a stew pot as a helmet.

Wallace was charged with first-degree reckless homicide and later pleaded guilty to a reduced charge of second-degree reckless homicide with a dangerous-weapon enhancement; he was sentenced in February 2017. Does anyone have information about the events that evening or the relationship between the two men?
