On August 13, 2023, 18-year-old Tyshon Johnson was shot and killed during a mass shooting in Washington Park, Chicago. The incident happened about 8:20 p.m. in the 5700 block of South Payne Drive, near the east end of the park and just west of Cottage Grove Avenue, close to the University of Chicago Medical Center. The violence began after a fight among a group of women; a male offender produced a gun and began firing. Johnson was trying to break up the altercation when he was struck in the thigh and buttocks.

Three other people were also wounded: a 16-year-old boy and another 18-year-old man, both shot in the legs or torso and reported in fair condition, and 52-year-old Aaron Rogers, who was riding his bike through the park and was shot in the face and chest. All victims were taken to the University of Chicago Medical Center, where Johnson was pronounced dead and Rogers was treated after biking himself to the hospital.

Johnson was a student at Englewood STEM High School preparing for his senior year; his mother, Yolanda, said he had been motivated to finish school in memory of his girlfriend, Deshawnay Yoakum, who had been killed in a March 2023 shooting. As of the latest reports, no arrests had been made and Area One detectives were investigating. If anyone has information that could help identify the shooter, please share it with investigators.
