An evening gathering at Arcadia Lake in Edmond, Oklahoma turned deadly on the night of Sunday, May 3, 2026. A large unsanctioned party promoted on social media drew many young adults; around 9 p.m. gunfire erupted during what witnesses described as an argument between two women that escalated and involved rival gang members. Dozens of shots were fired into the crowd. Eighteen-year-old high school senior Avianna Smith-Gray was struck in the head, underwent emergency surgery and died on Tuesday, May 5, 2026. At least 22 other people aged 16 to 30 were treated for gunshot and shrapnel wounds.

Authorities moved quickly to make arrests. On May 6, 2026, 18-year-old Jaylan A. Davis turned himself in and was initially charged with assault with a deadly weapon; that charge was in the process of being upgraded to felony murder after Smith-Gray’s death. He was held on a $1 million bond. A second person, 20-year-old Trinity Brown, was later arrested on charges of assault with a dangerous weapon and possession of a firearm after juvenile adjudication. Police said they believed at least one other suspect was involved.

Avianna’s family described her as vibrant, talented, loving, good with children, and looking forward to graduation. The shooting has prompted calls to review city policies on unsanctioned events and park security. If anyone who attended the May 3 gathering or has video or other information can help, please share what is known.
