A 40-year-old Oak Harbor man who had sex with an underage girl at a friend’s house will be going to prison.

Jason Brown pleaded guilty in Island County Superior Court Aug. 6 to indecent liberties.

Under the plea bargain, the prosecution and defense will recommend an exceptional sentence — beyond the standard sentencing range — of three years in prison. His sentencing hearing hasn’t been set.

The owner of the Oak Harbor home called the police early in the morning of Feb. 4 to report a rape. The woman said she caught Brown in her bedroom with a 13-year-old girl; they were both in their underwear and putting their clothes on, according to the report by Detective Jim Hoagland with the Oak Harbor Police Department.

In an interview with a detective, the girl said she and Brown had been hanging out and drinking, even though she told him she was just 13 years old. She said he started kissing and groping her in the kitchen, then took her to a bedroom and had sex with her.

The woman who owns the home interrupted the assault, kicked Brown out of the house and called the police.

Court documents state that Brown had moved to Oak Harbor from Wisconsin five weeks before the alleged assault. His criminal history includes two robberies, a theft and “battery by prisoners,” according to the police report.
