A Friday press release from Oklahoma County District Attorney Vicki Behenna’s office revealed two new suspects have been charged in relation to the May 3 Arcadia Lake shooting that left one 18-year-old dead and injured over 20 bystanders, with two of the four arrests made so far resulting in first-degree murder charges.

On May 6, Edmond police announced the arrest of Jaylan Davis, 18, who was allegedly the “primary aggressor” in the May 3 shooting, according to court documents. Behenna’s release on Friday announced Davis and Daviion Wyckoff, 21, now face six felony counts — including first-degree murder — after Avianna Smith-Gray died from injuries sustained during the shooting.

“My office has filed charges to hold those responsible accountable for the devastating violence that occurred at Lake Arcadia,” Behenna said in the release. “What should have been a gathering of young people ended in tragedy because firearms were brought into a situation where they never should have been. Avianna lost her life and our community continues to feel the effects. These charges are an important step toward justice.”

Aside from murder in the first degree, Davis was charged with possession of a firearm after juvenile adjudication. Wyckoff has been charged with possession of a firearm while on probation, and both defendants face further identical charges of:

  • Shooting with intent to kill;
  • Gang related offense;
  • Conspiracy to commit a felony; and
  • Possession of a firearm while in commission of a felony.

The first-degree murder charge is distinct from the felony murder charge that Behenna originally announced she would pursue against Davis in a May 6 press release. Oklahoma Title 21, Section 701.7 allows a person to be charged with felony murder “regardless of malice” if the person “takes the life of a human being during (…) the commission or attempted commission of murder of another person, shooting or discharge of a firearm or crossbow with intent to kill” or during the “intentional discharge of a firearm or other deadly weapon into any dwelling or building.”

Asked about the change, spokesperson for Behenna’s office Brook Arbeitman said “he was originally picked up on a charge the police thought was appropriate at the time.”

“But we determine what charges are actually filed. So after they screened the case with us, we filed first degree murder charges,” Arbeitman said.

Behenna’s office also identified Breonn Morton, 23, as an alleged accomplice to the crime. Morton has been charged with accessory to murder in the first degree. Court documents allege based on messages between Wyckoff and Morton that he aided Davis and Wyckoff by disposing of the firearms used in the shooting.

Morton is now the fourth suspect arrested in connection to the shooting. On May 12, 20-year-old Trinity Brown was arrested and charged with assault with a dangerous weapon and possession of a firearm after juvenile adjudication.

Law enforcement believe further arrests may be made.

“To date, Edmond Police have made four arrests in connection with this case, and investigators believe additional suspects remain outstanding,” Edmond Police Department spokeswoman Emily Ward said in a Friday press release. “The Edmond Police Department will continue to aggressively pursue all individuals involved and work alongside our law enforcement partners to bring those responsible to justice.”

Behenna’s press release also noted the investigation continues and more charges may be filed.

Affidavit: Shooting was ‘premeditated plan for retaliation’

According to a probable cause affidavit, Wyckoff’s involvement was revealed through the collection of “approximately 80 spent casings at the crime scene,” witness and victim interviews and the review of social media accounts. Court documents allege Wyckoff is a member of the 107 Hoover gang.

Court documents allege Davis — who was previously identified as a member of the North Highland Piru gang — and Wyckoff “did conspire and agree with each other to commit the crime of murder in the first degree (…) by shooting (Smith-Gray)” and planned “in advance to take firearms and drive to Lake Arcadia and shoot at individuals at a party.”

However, it was not explicitly stated in the affidavit if the defendants are alleged to have specifically targeted Smith-Gray.

The probable cause affidavit offers two pages of witnesses including a “Meta platform representative” and a family member of Smith-Gray’s.

Wyckoff was admitted to the hospital after a gunshot wound he sustained during the gunfire, the probable cause affidavit states. EPD detective Dakota Murley said he spoke with Wyckoff on May 4 and he denied any involvement. In a later conversation with his attorney, Wyckoff admitted to possessing a Draco and firing rounds from it during the party.

Murley obtained a warrant for Wyckoff’s phone records and discovered messages between Wyckoff and Davis. Davis told Wyckoff he had been robbed by another gang and a gun was stolen from him. Wyckoff also sent Davis an audio message about killing someone.

Earlier in the day May 3, Wyckoff and Davis discussed going to Lake Hefner where Murley discovered another party was occuring though “many of those attendees left and went to the party at Arcadia Lake,” the affidavit said.

Murley assessed the conversations, which included a text message in which Davis said he would be out that night “shooting at” people, as a “premeditated plan for retaliation.”

Murley also found a video of Davis sent May 3 before the shooting where he is “observed speaking to a female, mentioning that he would not shoot her, but would shoot anybody who talked to her.”

The defendants are set to have a same-day initial arraignment that is yet to be scheduled.
