Nobody was injured when someone fired a handgun into an Oak Harbor home and nearby vehicles this past week, according to the Oak Harbor Police Department.

The Tuesday incident was the third drive-by house shooting on North Whidbey since April, but investigators don’t know if any of them are linked or what the motive might be.

“We’re a little stumped,” Detective Sgt. Jim Bailey said.

At 10:48 p.m. on Dec. 9, officers responded to a report of a shooting on Southwest Roeder Drive. Several neighbors reported hearing the sound of gun shots and of a vehicle leaving the area, according to the police.

Officers located several shell casings from a handgun. They canvased the area and located bullet holes in one home and vehicles parked in the driveway, the police reported.

In July, an unknown person armed with a handgun fired at least five shots on Castilian Way. A bullet hit the house, one hit the garage and the rest struck two parked cars.

The Island County Sheriff’s Office investigated a drive-by shooting of a home on Swantown Road on April 22. Someone fired several shots and hit two houses with what investigators believe was a small-caliber handgun.

Nobody has been injured in any of the shootings.

Detectives with the Oak Harbor police are looking for additional witnesses or information. Anyone with information should contact the police department at 360-279-4600.
