A community trail ride outside Roseland, Louisiana, on August 8, 2020, ended in tragedy when gunfire erupted and 21-year-old Zion Hutcherson of Baton Rouge was struck by a stray bullet and killed. Hutcherson, a mother to a young toddler, had been attending the event with her sister; several other people were wounded in the same outbreak of violence.

Investigators tied the shooting to an exchange of gunfire between rival local street gangs. Over the following days and weeks the Tangipahoa Parish Sheriff’s Office identified multiple people in connection with the case. Brandon Perry, 30, and Tommie Diamond, 23, were charged with second-degree murder; Raheem Harold, 19, faced second-degree murder and two counts of attempted second-degree murder; Laqontre Deonte Turner, then 22, was later charged with second-degree murder; Craig Brown, 29, and Raven Warford, 27, faced negligent homicide-related charges.
