Anchorage police say a teenage boy, the second of two people who died in two hours Friday night during separate Mountain View shootings, was killed by another teen who gave the gun he used to a man.

APD spokesman MJ Thim said Saturday that both the suspected shooter and the man, 19-year-old Michael Marquez, were in custody. Their arrests followed intensive police work and a “high-risk search” for suspects in the North Bliss Street shooting reported at about 6:20 p.m. Friday.

The victim, a 15-year-old boy initially reported Friday to be 16, has not been identified pending notification of his next of kin.

In a statement, police said the shooting occurred during an altercation on the 500 block of North Bliss “a group consisting of juveniles and late-teens.”

“During the altercation, the juvenile male suspect shoots the victim in the upper body, hands off the gun to [Marquez] and flees on foot towards the apartment building where officers conducted the high-risk search,” police wrote.

Thim didn’t have immediate word from investigators Saturday on how many people were present during the encounter, why they were there or why the victim was shot.

“What they were doing there on the street, what happened, what caused the altercation -- that's all part of the investigation,” Thim said.

Marquez was taken into custody later Friday evening in the immediate area, and the alleged shooter was arrested at about 4:30 a.m. Saturday on the 700 block of North Flower Street. Marquez was charged with evidence tampering, while the juvenile was taken to the McLaughlin Youth Center on charges being forwarded to the state Division of Juvenile Justice.

No further suspects are being sought in the North Bliss Street shooting, Thim said, which is considered a separate homicide case from an earlier shooting nearby on the 600 block of North Hoyt Street at about 4:45 p.m. Friday. A woman in her 20s, found dead in an apartment during what was initially reported as an accidental shooting, hasn’t been named because her family hasn’t yet been notified.

No charges have yet been filed in the North Hoyt Street death, which police consider a suspicious incident, but police believe they have spoken with everyone involved. Detectives were still following up on leads Saturday, as Thim offered his condolences to Mountain View residents after the deaths.

“The community is mourning and in shock about both of them, and our thoughts and prayers are with them and their families and their friends,” Thim said.
