A 19-year-old man is accused of stabbing a teenage boy to death last week at a home in Utqiagvik, formerly known as Barrow, where the victim’s relatives said the suspect had been staying.

The Alaska Dispatch News reported that 14-year-old Crawford Sue Patkotak died Wednesday. His father, Arctic Slope Regional Corp. head Crawford Patkotak, said that the stabbing was committed by a nephew with mental illness who had been taken in by the family.

Court records show Harry O. Ahkivgak, 19, was charged Monday with first-degree murder. A criminal complaint against Ahkivgak, written by Detective Sgt. Nicolas Gueco, III, said police were called at about 7:15 a.m. Wednesday to the Samuel Simmonds Memorial Hospital, where Crawford Sue Patkotak was declared dead less than an hour later.

The victim’s brother told police he was awakened by Crawford Sue Patkotak, who had chest and neck wounds. The brother tried to call 911 but couldn’t get through due to poor reception, so he drove Crawford Sue Patkotak to the hospital in his truck.

Police found Ahkivgak outside the home, standing on a boat and holding a knife, with “multiple stab wounds on his legs.” Ahkivgak told the officers he had injured himself, Gueco said; he dropped the blade when police ordered him to and was medevaced to Anchorage for treatment.

Ahkivgak discussed the stabbing with a relative, Gueco said, who spoke with police. According to the relative, lights in the Patkotak home flickered when they were turned on – but Ahkivgak said residents had been “messing with the lights to give me a seizure.”

“[The relative said] Harry said he was getting mad thinking they were picking on him, giving him seizures,” Gueco wrote. “[The relative said] Harry told him he stabbed [the younger Patkotak] on the neck and after that, he was full of anger and hate.”

No proceedings in the case against Ahkivgak were listed in court records Tuesday.

North Slope Borough officials declined to discuss details of the case with KTVA last week and didn’t immediately answer requests for further comment Tuesday morning.
