Teenage suspect in fatal hit-and-run collision turns herself in to deputies

Deputies ID’d the 15-year-old as the suspected driver in the fatal collision of a Maple Valley man.

A King County judge has found probable cause to charge a 15-year-old driver with murder on Sept. 10 after the driver turned herself in for allegedly killing a Maple Valley man in a hit and run collision in July.

The 15-year-old alleged driver in the July fatal collision turned herself in to detectives on Thursday, Sept. 9, according to the King County Sheriff’s Office, only a day after the agency announced they had identified her as a suspect and recovered the vehicle from the incident.

Greg Moore, 53, was fatally struck while out for a morning run in the 23800 block of SE 216th Street near Maple Valley on Sunday, July 18. A swell of community support and tips helped detectives make progress in the case, according to the sheriff’s office, leading to their Sept. 7 announcement that detectives had recovered the Toyota Camry involved in the crash and were processing it for evidence.

The judge found probable cause for charges of second-degree murder and hit and run. The teen did not appear at the hearing and remains in custody. Due to her age, juvenile court does not provide first appearance documents in the same way as provided in adult cases in district court.

A charging decision and documents are expected Tuesday, Sept. 14.

The suspected driver of the vehicle was still at large when the sheriff’s office announced Sept. 8 that they had found the vehicle and identified her as a suspect. The agency has not yet publicly named her.

The day after that announcement, the agency said, the girl surrendered without incident at the agency’s SeaTac precinct.

“We hope this arrest brings some closure for Greg’s family and a community touched by his loss,” the sheriff’s office said in a statement.

“Nothing will bring Greg home, but I want to express my heartfelt thanks to the MARR (Major Accident Response and Reconstruction) detectives who have worked this case tirelessly since July,” King County Sheriff Mitzi G. Johanknecht said in a prepared statement. “I also want to express my gratitude to the Maple Valley community, who refused to let Greg’s memory fade.”

Detectives used headlight fragments found near the scene, along with surveillance and other evidence, to track down the Toyota Camry. Detectives believe this Camry may have been traveling with another vehicle, around 6:15 a.m., in the vicinity of the collision with Moore, who was found along the roadside.

Moore grew up in Issaquah lived in Maple Valley for over 25 years, according to information posted by his wife Michelle Moore on a gofundme.com account for Greg Moore started in July. The account had raised $38,710 as of Sept. 10.

Moore posted on Sept. 3 that funds would be used to help find the driver of the hit-and-run.

“I want to thank everyone for their generosity and support,” Moore said. “We have decided to use some of the funds raised here to hire a private investigator for this case. If we receive no tips leading to an arrest by 10/18/2021 the remaining funds will be used for funeral expenses and bills.”

She said people could get a refund of their money if they disagreed with that plan.
