On the morning of January 25, 2026, 36-year-old Joselynn Diaz-Garcia was found unresponsive in the backyard of her Joliet home on Garnsey Avenue, the apparent victim of a homicide. Her 4-year-old son, Gianni Reyes, was also found fatally shot at the scene after neighbors called 911 reporting gunshots.

Police identified a man believed to be responsible as 29-year-old Joseph D. Johnson, described as a part-time resident of the house. Johnson was located at the scene with what authorities said appeared to be a self-inflicted gunshot wound to his ankle; he was taken to a hospital. Investigators said the incident initially appeared to involve a domestic disturbance and that a motive was still under review.

The community remains shaken by the deaths of a mother and her young child. If anyone has information about Joselynn, Gianni, the household, or the events leading up to January 25, please come forward to local authorities.
