A Baton Rouge man has been put on probation after he admitted firing a gun into the ground outside the Baker Civic Club to disperse the crowd in the chaotic aftermath of a 2014 shooting inside the club that left three teenagers dead.

Donnie Cavalier, 25, who has said he was helping provide security for a birthday party and rap concert at the club that night, pleaded guilty Friday to a misdemeanor charge of illegal carrying of a weapon.

State District Judge Tony Marabella put him on supervised probation for one year, fined him $300 and ordered him to perform 100 hours of community service and forfeit the weapon.

Cavalier’s plea came two weeks after Nakeydran Williams, 17, also of Baton Rouge, pleaded guilty to three counts of manslaughter and one count of attempted second-degree murder and was sentenced to 40 years in prison.

Williams, who was 16 at the time of the March 2014 shooting, admitted firing the shots that killed 15-year-olds Kendal Dorsey, of Baton Rouge, and Marcell Franklin, of Zachary, and 18-year-old Baker High School senior Diontrey Claiborne. The attempted murder charge involved the wounding of Javaughn Simmons, who was 19 at the time.
