On the evening of July 19, 2026, a gathering at Savannah Williamson Community Park in Denmark, Tennessee, ended in a mass shooting that left 36-year-old Garrion Duke Greer and two others dead. Greer, known as Duke, was a father of two. The event escalated into a chaotic shootout in which about 12 people were killed or injured.

Investigators say occupants of a silver Honda Accord and a white Nissan Altima were seen near the park just before gunfire began. Authorities allege occupants of the Honda Accord fired into the crowd and people at the party returned fire. The Madison County Sheriff’s Office, with assistance from multiple agencies, identified and arrested four suspects: Rodney Parker, 21, of Medon; Roshod Parker, 19, of Medon; Ladarius Grimes, 21, of Jackson; and Tomorris Person, 18, of Jackson. Each was charged with three counts of felony murder in the perpetration of attempted first-degree murder.

The investigation remains active and officials say additional arrests or charges are possible. Did anyone at Savannah Williamson Park that night or someone who knows the victims or the vehicles have information to share?
