A member of the Navy who admitted using cocaine agreed to be a confidential informant for law enforcement and was involved in a series of controlled buys of the drug in Oak Harbor last year, according to court documents.

The joint investigation was conducted by the Naval Criminal Investigative Service, the Oak Harbor Police Department and the Island County Sheriff’s Office.

The Navy member agreed to be a confidential informant in order to receive favorable treatment from the Navy, according to the Oak Harbor police report.

The confidential informant claimed to have previously purchased cocaine from two dealers in an Oak Harbor bar.

During the undercover operation, the confidential informant purchased suspected cocaine three times from a man and a woman in parking lots while law enforcement observed from an “undercover vehicle,” according to the Oak Harbor police report.

A fourth time the confidential information attempted to purchase cocaine, but the white powder tested negative for cocaine, and the dealer later admitted it was inositol powder, the report states.

Following the final undercover operation, the two suspects were arrested on suspicion of dealing cocaine.

The woman said she didn’t know her boyfriend was dealing drugs and denied delivering cocaine to anyone, the report states.

This month, prosecutors charged the woman, Ashlee Steen, in Island County Superior Court with a delivery of cocaine and conspiracy to deliver cocaine. If convicted of both charges, she could face 20 to 60 months in prison under the standard sentencing range.

Officials did not say why the man wasn’t also charged.
