A 15-year-old Oak Harbor boy was arrested last week for allegedly making online threats to shoot students at North Whidbey Middle School.

Oak Harbor Police Chief Ed Green said there is no evidence that the homeschooled boy actually had access to a firearm, but that such threats are taken very seriously by police.

Officers don’t know what the motive was and are still investigating, Green said.

“We’re not sure what the catalyst was,” he said.

The reported threats were directed at three students, Green said.

The police report indicates that the threats were first reported to police on Dec. 29. The suspect allegedly used a fake name on Facebook and made the threats to shoot students at the school after the holidays.

In addition, the boy is suspected of sending instant messages over Facebook to a pre-teen girl asking her to send nude photos and boasting that he was going to shoot someone at the school, the report states.

The boy was arrested at his home Jan. 2 on suspicion of two counts of making threats to kill and one count of cyberstalking. His bail was set at $5,000.

Because the suspect is a minor, the newspaper is not identifying him by name.

The case was the second gun-related threat made involving North Whidbey Middle School in the last few months.

On Halloween, a 14-year-old student was arrested after texting a message that he was going to shoot up a school dance.
