Three women were hospitalized Sunday after sustaining injuries in an early morning car accident north of Oak Harbor.

According to a Washington State Patrol news release, the accident occurred at about 4:25 a.m. on Highway 20 near the intersection of Monkey Hill Road. A northbound traveling vehicle, a 2006 Nissan Altima, reportedly crossed the centerline and stuck a 1996 Saturn 4D that was traveling southbound in the other lane.

In the Nissan were Leticia Rincon-Garcia of Burlington, 25, and Janet Estrada of Mount Vernon, also 25. At the time of the news release, the state patrol was still trying to determine who was driving the vehicle as the women were out of the car being treated by emergency responders when police arrived.

Both women were transported to Island Hospital in Anacortes. A hospital spokeswoman confirmed that they have since been treated and released.

Driving the Saturn was Maria Whitmore, a 60-year-old Oak Harbor resident. She was transported to Whidbey General Hospital in Coupeville where she remains in satisfactory condition.

Both vehicles were totaled, the release said.

The Washington State Patrol is investigating whether or not alcohol or drugs were factors in the collision. As of Sunday morning, no charges had been filed.
