EDMOND, OK − An 18-year-old man was arrested on Wednesday, May 6, in connection with a mass shooting that left one woman dead and 22 others injured at an "unsanctioned party" by an Oklahoma lake, police said.

Jaylan Davis, of Oklahoma City, was arrested on a charge of assault with a deadly weapon in response to the shooting, according to police. Gunfire erupted during a nighttime party on May 3 at Arcadia Lake near the Scissortail Campground in Edmond, a suburb of north Oklahoma City.

During a news conference on May 6, Edmond Police Chief J.D. Younger said the initial charge against Davis was in the process of being upgraded to felony murder after an 18-year-old woman died from injuries sustained during the shooting. Police identified her as Avianna Smith-Gray.

Oklahoma County District Attorney Vicki Behenna confirmed in a news release that Davis will be charged with felony murder in the first degree over the shooting death "at the unsanctioned gathering." His bond had been set at $1 million on a complaint of assault and battery with a deadly weapon.

Investigators believe the incident began with a "disturbance" between two people attending the gathering and escalated into an altercation between rival gang members, Younger said. Authorities also believe that there is at least one more suspect in the shooting.
