A 19-year-old Tukwila man was sentenced Friday to 18 years in prison for the 2012 stabbing death of Jasmyn Tully, 17, of SeaTac.

Kolby Jordan Clark pleaded guilty in March to second-degree murder. He was 17 at the time of the murder but was charged as an adult under state law because second-degree murder falls under the serious violent offense of a Class A felony.

Clark faced a sentence range of 12 to 20 years in prison, according to the King County Prosecuting Attorney’s Office. King County Superior Court Judge Bill Bowman sentenced Clark at the Norm Maleng Regional Justice Center in Kent. Prosecutors recommended 16 years.

Tully was found in an apartment in the 11600 block of 42nd Avenue South by Tukwila Police officers at about 3 a.m. March 17, 2012, unconscious and suffering from stab wounds, according to Tukwila Police. She was transported to Harborview Medical Center in Seattle by Medic One but died a short time later.

Officers questioned Clark, who lived at the apartment. Police arrested Clark and booked him into the King County Youth Services jail for investigation of second-degree murder.

Tully had a stab wound to her neck as well as defensive wounds to her right hand, according to charging papers.

Both Tully and Clark had been spending the night at the apartment rented by other residents. Clark had left the apartment when police arrived, but officers found him about 15 minutes later several blocks from the apartment walking on the street without any shoes. He had a cut to his left wrist.

Clark initially claimed he had been attacked by a man. The teen later told detectives he had killed Tully, according to court documents. Clark said after Tully fell asleep, he felt an urge to hurt someone.
