From the SPD Blotter
On July 14th at approximately 11:38 p.m. officers responded to a campground in the 5200 block of 35th Avenue SW for a report of a domestic disturbance between a boyfriend and girlfriend. The suspect, a 20-year-old male, threatened his girlfriend with a gun. The victim was not injured and no shots were fired. The suspect fled the scene prior to the arrival of responding officers.

Officers continued to search for the suspect and information developed during the course of their investigation led them to the suspect’s residence in the 5000 block of Delridge Way SW. Officers surrounded the residence and subsequently saw the suspect through a window in the house however, the suspect refused to come outside and surrender to officers.

The SWAT team and negotiators were called to the scene and thus far negotiators have been unable to get the suspect to come outside. Three other adult males believed to be roommates of the suspect have come out and were all interviewed and released. There may be one other roommate still inside the house with the suspect.

This incident is on-going and we are trying to come to a peaceful resolution.
