A Hawaii-born 27-year-old man was a victim in a double homicide in Washington state last week, investigators from the Vancouver Police Department said.

On Feb. 1, Christopher M. Haske, 27, was found dead with another man, Kenneth W. Koltz, 32, at a home on Northeast 40th Circle in Vancouver, Wash.

Both men died due to a gunshot wound to the head, according to the Clark County Medical Examiner.

At about 3:15 p.m. that day, Vancouver police responded to a call from a relative of one of the men who had visited the home and discovered the two bodies. The relationship of the two victims is unknown at this time, police said.

The Vancouver Police Department Major Crimes Team is investigating the case and interviewing possible witnesses but has released few details, including how the two men were allegedly killed.
