Deputies arrested a 48-year-old Langley woman Monday who was chasing a hallucination around her neighbor’s yard while high on various drugs and armed with a handgun, court documents indicate.

Dana McDonald appeared in Island County Superior Court Monday afternoon and looked so dazed that the judge remarked about her intoxication.

Judge Vickie Churchill found that there was probable cause to believe that McDonald had illegally possessed a firearm. A deputy allegedly caught her with a loaded .38-caliber revolver.

Churchill noted that McDonald had been hallucinating and allegedly admitted to being sleep deprived and on drugs.

“That plus a gun is a bad mixture,” she said before setting McDonald’s bail at $20,000.

Prosecutors charged McDonald Tuesday with the unlawful possession of a firearm in the second degree. She had previously been convicted of robbery in Hawaii, so she’s not eligible to possess a gun.

If convicted, McDonald could face from three to nine months in jail under the standard sentencing range.

Deputy Scott Davis with the Island County Sheriff’s Office responded to the report of a person yelling threats outside of a home on Saratoga Road.

He found McDonald in the woods near the house, armed with a gun and claiming she was chasing her estranged husband and his girlfriend.

While speaking with the deputy, McDonald repeatedly pointed in different directions and claimed that she could see her husband pointing a gun at them. The deputy looked and saw nothing.

McDonald admitted that she was “sleep deprived, intoxicated, had smoked marijuana and over-medicated with Oxycodone,” Davis wrote.

In court, Senior Deputy Prosecutor Eric Ohme said McDonald’s husband had recently been arrested for second-degree assault for allegedly firing a pistol near her head.

Attorney Peter Simpson, who was representing McDonald, said the incident was possibly a case of self defense, given the domestic abuse allegations.
