John Mitchell Sinegal Jr., 23, a Black man from Lafayette, Louisiana, was shot and killed in the early hours of April 9, 2021, after violence erupted at Bourgeois Park on Coliseum Boulevard beside the University of Louisiana at Lafayette. University police were called about 2:11 a.m., but Sinegal had already been taken to Ochsner Lafayette General Medical Center, where he was pronounced dead.

Investigators described a gathering that turned tense and then deadly, with officers saying multiple people were involved and others put in danger by gunfire; later filings included multiple attempted-murder counts alongside the homicide charge. Within a week, Jayvien Jawane Mallery, 20, was arrested and booked as a principal to second-degree murder with three counts of attempted first-degree murder and a carrying-a-firearm-on-school-property charge. Tyquan Trekel Marshall, 22, turned himself in and was booked on second-degree murder, three counts of attempted first-degree murder, and carrying a firearm on school property. Zykeivrik Jaudan Narcisse, 21, was also arrested and charged with accessory after the fact to second-degree murder and the attempted-murder counts.

The arrests supplied names and faces but not answers about why the confrontation occurred. If anyone witnessed the April 9 gathering at Bourgeois Park or has information about what led to the shooting, please share what is known.
