PORT ORCHARD — Eli Gregory, the third suspect alleged to have been involved in the murder of 19-year-old Tyrone Sero, turned himself in to deputies from the Pierce County Sheriff’s Office early Friday morning.

Authorities said the 18-year-old Gregory called the sheriff’s office to turn himself in after being at large following the murder. Deputies took the suspect into custody without incident around 3:30 a.m. and was transferred to Kitsap County Sheriff’s Office deputies.

A felony arrest warrant had been issued by KCSO for Gregory earlier this week in connection with Sero’s slaying.

Two other suspects were arrested by authorities Oct. 21, including 19-year-old Kannon Anthony Stephens of Gig Harbor, who told detectives he shot Sero of Port Orchard in the back of the head during a marijuana drug deal gone bad in South Kitsap early in the morning on Oct. 20.

Court documents allege that the second suspect already in custody, 20-year-old Karlen Merle Talent of South Kitsap, was an accomplice in Sero’s murder. Both men are being held in jail on a first-degree murder charge with bail set at $1 million. Both men pleaded not guilty in court.

“Sheriff John Gese and the men and women of KCSO want to express our sincere appreciation to our law enforcement partners, as well as our partners in the media and the public, who helped us to locate Gregory and get him into custody,” KCSO said in a Facebook post Friday morning.
