Four males — ages 20, 18, 17 and 16 — face first-degree murder and first-degree robbery charges in the fatal shooting of a 13-year-old Kent boy July 16 at a Kent park.

King County prosecutors charged three more males July 30 in the death of Matthew Stavkoviy, who died of a gunshot wound to his back in the incident near Turnkey Park, 23300 100th Ave. SE.

King County prosecutors charged Faysal Abdullahi, 18, of Kent, on July 23, the first one arrested by Kent Police. Detectives took Abdullahi into custody July 18 at his Kent home. He remains in custody at the King County Correctional Facility in Seattle with bail set at $2 million. He is scheduled to be arraigned Aug. 5 in Courtroom GA of the Maleng Regional Justice Center in Kent.

Brothers Diaviante Dunmore, 20, and Marsais Dunmore, 16, are each being held on $2 million bail. Prosecutors decided to charge Marsais Dunmore as an adult, which is allowed under state law when a juvenile age 16 or 17 commits a felony. Marsais Dunmore also faces a second-degree unlawful possession of a firearm charge because he is under 18.

The brothers are scheduled to be arraigned at 9 a.m. Aug. 12 in Courtroom GA of the Maleng Regional Justice Center in Kent.

Police arrested the brothers July 25 at a Covington apartment complex.

Semarias Woods, 17, of Kent, came with his mother and a family friend to the Kent Police Station July 26 to turn himself in, according to charging documents. Woods also is being charged as an adult and will be arraigned along with the Dunmore brothers. All three are in custody, with Diaviante Dunmore at the King County Correctional Facility in Seattle while the other two are at the juvenile detention center in Seattle.

According to charging papers, Abdullahi reportedly arranged through OfferUp, an app for selling items, to meet a friend of Matthew’s who was selling camera equipment, and to rob him of the camera gear. Diaviante Dunmore reportedly joined Abdullahi at Turnkey Park to make the deal.

Woods allegedly served as the getaway driver and parked in an apartment complex near the park, according to charging documents.

Marsais Dunmore allegedly appeared shortly after the other two at the park and fired a shot. Diaviante Dunmore said during an interview with detectives that caused a panic and he and the male selling the camera gear ran into each other. Diaviante Dunmore said he grabbed the backpack holding the camera gear and the three of them ran back to a Ford Fusion parked in the Olympic Skyline Apartments.

Matthew and his 15-year-old sister jumped on their ATV after the shot was fired to flee the park. As they drove away, more shots reportedly were fired by Marsais Dunmore and one hit Matthew.

Diaviante Dunmore said the shooting was never supposed to happen, according to charging papers. He said the gun was there in case something goes wrong. He admitted they planned to take the camera gear without paying.

“These co-defendants worked together as accomplices to orchestrate an armed robbery in a neighborhood park on a 15-year-old victim,” wrote Senior Deputy Prosecuting Attorney Thomas O’Ban in charging papers. “These co-defendants left a 13-year-old bystander dead and narrowly missed striking his 15-year-old sister with bullets.

“The co-defendants then fled the scene and evaded law enforcement until the thorough investigation by Kent Police Department detectives made continued evasion impossible.”

Detectives used IP addresses from the OfferUP records and cellphone records to track down home addresses for Abdullahi in Kent and the two brothers. Detectives recovered some of the stolen camera equipment from Abdullahi’s residence.

Detectives also seized the vehicle reportedly used in the crime, which belonged to the father of the Dunmore brothers.

Local athletes

The Dunmore brothers each played football at Kentlake High School, according to sports websites. Diaviante Dunmore was a wide receiver in 2022 and graduated in 2023, according to 247sports.com. Marsais Dunmore also played football at Kentlake and is a member of the Class of 2025, according to hudl.com.

Diaviante Dunmore also played basketball at Kentlake, according to hudl.com.

Woods is listed as a member of the Kentlake Class of 2026 and as a football player, according to hudl.com.

Matthew active in church

Matthew, 13, played an active role at Bread of Life Church in Kent, according to church videos.

The church held a prayer service for Matthew just one day after he was shot.

One of the speakers described Matthew and his family as being very involved in the church. Matthew would sing songs, preach sermons and read bible verses.

“I see a big setback for the family,” the speaker said. “Maybe in two or three years from now he (Matthew) would have been helping the father and brother with their work. In two or three years, he could have been plugged into this church as a minister and a powerful preacher like his brother.”

The church posted a video on its Facebook page of the Stavkoviy family singing in front of the church from three years ago, when Matthew was 10.

A Celebration of Life Service was held for Matthew on Sunday, July 28, at Way to Salvation Church, 1119 Central Ave. S., in Kent. Burial was July 29 at Enumclaw Evergreen Memorial Park.
