On August 9, 2023, a domestic dispute in unincorporated Crystal Lake, Illinois, ended in a deadly shooting at a Wild Plum Road residence. Deputies responding to a 911 call at about 3:56 a.m. found three women dead at the scene: 32-year-old Lauren Smith-Song, 49-year-old Yuna Song, and 73-year-old Chang Song. A fourth woman, who had made the emergency call, was seriously injured and taken to hospital; she has since been released.

A 44-year-old man, Jean Song, was also critically injured and later died at the hospital. Investigators concluded the violence began as a domestic dispute and that Jean Song shot the four women before turning the gun on himself. The McHenry County Sheriff’s Office said Song was likely experiencing a mental health crisis and noted he held a valid Firearm Owner’s Identification card and a concealed carry license. Neighbors described the neighborhood as tight-knit and were shocked by the deaths.
