On the afternoon of February 1, 2011, a relative entered a home at 12007 N.E. 40th Circle in Vancouver, Washington, and found two men dead. One victim was Kenneth W. Koltz, 32, who lived at the residence; the other was 27-year-old Christopher M. Haske, also a resident. Police and emergency services were called about 3:10 p.m., and the Vancouver Police Department Major Crime Unit later determined both men were homicide victims.

Early accounts suggested the men had been shot, but authorities did not publicly confirm the official causes of death and withheld autopsy details. The house, in the Image neighborhood behind the SEH America plant, was owned by another person; voting records list Koltz as a resident. Detectives did not identify suspects or a motive in the days after the killings.

If anyone knew Kenneth Koltz, his routines, acquaintances, or saw anything unusual around that address on February 1, 2011, please come forward with information.
