This unsolved double murder does not appear to be an active "cold case" on any of the lists. It was originally (and probably still is) in the jurisdiction of the Detroit Police. I brought it to the attention of the newly formed Michigan Cold Case investigation group, but have not heard anything regarding any recent efforts to reopen or reinvestigate it.
Pat Brown (17) and his close friend Sheldon Miller (14) were outside in the Milan Park, only a block from their homes at about 10:30 pm the evening of 3 July 1964. They purchased some fire crackers from another youth and were setting them off - as were many other kids that evening.
Some time about 10:30pm, they were gunned down by an unidentified person using a .22 revolver. Their assailant walked away from them about 78 feet, ejected 8 spent shell casings and one live round from the gun's cylinder, reloaded and returned to shoot them again, ensuring that they died by shooting each boy in the head.
Their lifeless bodies were found shortly after midnight on 4 July 1964 by two other boys out walking a dog, who reported the murder to police. An extensive investigation followed involving the entire Detroit Police department. Newspaper coverage was also extensive, until a city-wide newspaper strike occurred.
By the time six months passed, only three Detroit Police detectives were still working on the case. Although hundreds of leads had been followed, witnesses identified and questioned, and evidence gathered and studied, no viable suspects were identified or charged with the murders.
