Around 9 p.m. on Sunday, May 3, 2026, gunfire erupted at a large outdoor party at a campground near Arcadia Lake, a popular recreational reservoir located 13 miles north of Oklahoma City in Edmond, Oklahoma. At least 13 people were hospitalized — 10 at Integris Health Baptist Medical Center in Oklahoma City and 3 at Integris Health Edmond Hospital — with victims described as being in “various conditions.” Several additional people drove themselves to medical facilities. No suspects are in custody as of Monday morning.
Edmond Police Department spokesperson Emily Ward confirmed that officers were “all over the metro speaking with victims and witnesses” and that police believe there is no ongoing threat to the public. The gathering appeared to be a ticketed event called Sunday Funday that had been advertised on social media. The shooting is among more than 130 mass shootings with 4 or more victims recorded in the United States so far in 2026, according to the Gun Violence Archive.
Shots Fired at a Large Young Adult Gathering Advertised on Social Media as Sunday Funday
Edmond police received reports of shots fired at approximately 9 p.m. local time Sunday at a campground near Arcadia Lake. Ward described the gathering as a “large party” attended primarily by young adults. A flyer circulating on social media prior to the shooting advertised an event called Sunday Funday at the location, suggesting the gathering was a planned, publicized event rather than a spontaneous assembly. Organizers of the event posted online after the shooting asking for prayers and apologizing to attendees.
Arcadia Lake is an artificial reservoir built for flood control that has become one of the most popular recreational destinations in the Oklahoma City metropolitan area, offering camping, fishing, boating, picnicking, and water sports. The campground where the shooting occurred is within the city limits of Edmond, a suburb of approximately 100,000 residents. The area around S. Air Depot Boulevard near the lake was blocked off by police following the shooting, according to AP photographs from the scene.
No Arrests Made as Police Spread Across the Metro to Interview Victims and Witnesses
As of Monday morning, no suspects had been identified or arrested. Ward told reporters at the scene that investigators were actively working to locate those responsible. “We are working extremely hard to find these suspects and help these victims,” she said. Police have stated they believe there is no ongoing public threat, though investigators have not released details about the number of shooters, the weapons involved, or how the confrontation began.
The investigation is being handled by the Edmond Police Department with assistance across the metro area. Authorities have not released the names or ages of any victims. Ward acknowledged the shooting was “a very terrifying situation” and indicated that the police response extended well beyond the lake itself, with officers interviewing people at multiple locations throughout the Oklahoma City area.
The Arcadia Lake Shooting Is Part of a Weekend Pattern of Mass Shootings Involving Young People
The Arcadia Lake shooting was one of three mass shootings involving teenagers or young adults that occurred across the United States over the same weekend, a cluster that drew national attention to the ongoing frequency of gun violence at gatherings of young people. The Gun Violence Archive, which tracks incidents with 4 or more victims, has recorded more than 130 mass shootings in the United States in 2026 as of May 4. At least 278 young people between the ages of 12 and 17 have been killed by gun violence so far this year, with another 796 injured, according to GVA data.
Edmond itself carries a grim place in the history of American mass shootings. On August 20, 1986, postal worker Patrick Sherrill opened fire at an Edmond post office, killing 14 coworkers and injuring 6 others before taking his own life. The Arcadia Lake shooting now adds a new entry to the city’s record, this time at a recreational gathering rather than a workplace, and with a far younger set of victims and witnesses.
Conclusion
Thirteen people were taken to hospitals after someone opened fire on a crowd of young adults enjoying a Sunday evening at an Oklahoma lake. The suspects have not been found. The victims’ conditions have not been fully disclosed. The investigation is active and expanding across the metro. What is known is that a popular public gathering place became a crime scene in minutes, and that the people who organized Sunday Funday are now apologizing online while detectives work through the night. This is a developing story.
