Case details
According to the criminal complaint, on June 19, a Milwaukee County Sheriff’s Office detective responded to Washington Park in Milwaukee.
Dispatch told the detective that there were about 50 people on the north side of the park who were fighting. He saw the group of people, juveniles between 14–18 years old, yelling and moving in groups.
While monitoring the crowd to determine the aggressors in the fight, the detective heard five gunshots and when he tried to figure out where the shots came from, he heard fully-automatic gunfire from the same area.
The detective saw a black male with a thin build wearing a gray hooded sweatshirt with his arm in the air and holding a tan and black pistol. The detective noted a silver device on the rear of the slide, which he knew to be a "switch" that makes a semi-automatic firearm function as a fully-automatic weapon, per the complaint.
The person with the automatic firearm, later identified as Onterio Girley, continued to fire multiple bursts of gunfire from the weapon that he was holding in his hand. With his back to the detective, Girley leveled his weapon out towards the crowd as he ran away. The detective, in an unmarked squad car, followed Girley to try and apprehend him.
The detective used his squad car to follow Girley. He positioned his squad in a way to disrupt Girley's path, which caused Girley to be hit by the vehicle. Girley was taken into custody, and his firearm was found near the area where he ran away.
The next day, another detective spoke to the 15-year-old at Children's Wisconsin, who was being treated for gunshot wounds sustained at the shooting at Washington Park. He was also taken into custody related to the shooting death of 17-year-old Sherrone Thornton.
