An argument precipitated a shooting which left three people dead and 15 others injured during a May Day party hosted by residents in the small community of Stockton, Alabama, Saturday night.

The Baldwin County Sheriff’s Office said deputies were alerted to gunshots about 9:30 p.m. at the event, which was held in an open field on Upper Bryant’s Landing Road and attended by an estimated 1,000 people.

Witnesses told investigators the event had been peaceful until an argument began between an unknown number of people, leading to at least one person brandishing a weapon and firing multiple rounds into the large crowd.

“We do believe there may have been more shooters, and we are following up on those leads,” Baldwin County Capt. Andre Reid said late Sunday afternoon.

Three people died during the shooting. While the sheriff’s office has not released the names of the victims, WALA has reported family members identified two of them as 37-year-old Chiquita Ewing and 24-year-o.d Christian Bradley.

Reid said investigators are counting on the public’s assistance in gathering information on the shooting.

“This is a tragic event that touches many lives in our community,” he said. “We are working very hard to bring this case to a resolution, but we cannot make arrests or successfully prosecute the offenders without help.”

Anyone with information is asked to contact the Baldwin County Sheriff’s Office at 251-972-8589.
