POULSBO — A 56-year-old man who is charged with first-degree murder pleaded not guilty in Kitsap County Superior Court Monday, relying on insanity as his defense.

Casey Cutlip of Poulsbo was arrested Feb. 21 for allegedly shooting his friend in the head. He remains in Kitsap County Jail on $1 million bail.

“It’s not that I think he’s insane now, [the plea] is based on temporary insanity at the time of the crime,” said Cutlip’s defense attorney, Tina Robinson. She said the defense is based on an evaluation by a psychologist; the state has requested its own psychological evaluation of Cutlip.

Cutlip called 911 after he admittedly shot the victim, Darwin A. Dunker, 74, three times in the head in Dunker’s apartment at Viking Crest Condominiums, 20097 Viking Crest Loop, Poulsbo.

At 9:53 p.m., sheriff’s deputies were dispatched to State Highway 3 and Tytler Road for a report of an “armed 56-year-old man making threats to harm another man who was not in that location.”

Poulsbo police began checking apartment complexes after the first 911 call. Ten minutes after the first 911 call, at 10:02 p.m., Cutlip called 911 and said he’d shot Dunker.

According to the prosecutor’s report, Cutlip said Dunker made sexual advances toward Cutlip in the victim’s apartment. Cutlip told the Poulsbo detective he repeatedly said no and “finally snapped, went home and got his .22 cal Beretta, returned to Dunker’s apartment and shot him in the head.”

Poulsbo Deputy Police Chief Wendy Davis said the two men were known to have been friends for several years.

“This was not a random situation, but it still shakes the community and we understand that,” Davis said. “We’re addressing concerns and addressing these situations as they come up.”

Cutlip’s trial is set for Aug. 14.
