On the afternoon of July 14, 2020, Seth Robertson, 36, was working at Brownsburg Cemetery near North Grant Street and 56th Street when a vehicle arrived and its driver, 22-year-old Joshua Hayes, exited and opened fire on the two cemetery workers. The men fled in different directions; Hayes chased Robertson toward 56th and Grant, caught him and shot him multiple times, killing him at the scene.

Hayes then pursued the second worker through a residential area and back onto 56th Street. A passerby with a legal carry permit witnessed Hayes pinning that man and aiming a gun at his head, fired at Hayes, and struck him. Hayes was pronounced dead at the scene; the second worker survived and was treated for injuries. Investigators described the attack as apparently random, found no prior connection between Hayes and the victims, and reported no evidence it was racially motivated, while noting potential mental illness in the assailant. The Hendricks County Prosecutor’s Office later declined to charge the armed motorist, ruling the shooting justified in defense of a third party.

Did anyone in Brownsburg know Robertson or the surviving worker and notice anyone suspicious near the cemetery that afternoon?
