PORT ORCHARD, Wash. – On Saturday, the Kitsap County Sheriff's Office announced that they found human remains during a murder investigation.

The human remains have been turned over to the Kitsap County Coroner's Office to be identified.

Two people have been arrested in connection to the death of 19-year-old Tyrone Sero who went missing in South Kitsap County this week, police say.

Sero, of Port Orchard, was last seen on surveillance video getting into an SUV Wednesday during what authorities say was a marijuana sale.

Kannon Stephens of Gig Harbor on Friday pleaded not guilty to murder while Karlen Talent, of Port Orchard, pleaded not guilty to being an accomplice.

Judge Tina Robinson kept their bail at $1 million.

Authorities say Stephens told police he heard a gunshot and thought Sero had shot his friend, so Stephens shot Sero.
