A two-car rollover accident near Dugualla Bay on North Whidbey resulted in five people being sent to the hospital Wednesday.

According to Washington State Patrol Trooper Norm Larsen, Oak Harbor resident Frances Antenucci was southbound on Highway 20 at about 6:20 when he attempted to make a left turn onto North Jones Road.

Larsen said Antenucci’s vehicle, a 1993 white and green Ford Bronco, was crossing the northbound lane of Highway 20 when it was struck by an oncoming 1997 maroon Dodge Grand Caravan.

The van was driven by Coupeville resident David Goodman, 49. Also in the vehicle was Christina Goodman, 45; Sarah Goodman, 16; and Brandon Goodman, age unconfirmed.

The violent collision crushed the front of the van and caused the Bronco to roll. One nearby resident said the crash was so loud that her husband looked out his front window in time to see the Bronco “flipping” through the air.

“It was a pretty loud crash,” echoed David Scott, an Oak Harbor resident who was waiting to turn left from North Jones Road onto Highway 20 at the time of the collision.

Scott and several other motorists jumped out of their cars to help the accident victims. First responders were on scene within a few minutes and all five people involved were transported to the hospital.

Whidbey General Hospital spokeswoman Trish Rose confirmed that the Goodmans were treated and released from the emergency department Wednesday, and that Antenucci was admitted to the hospital in stable condition and remains in hospital care.

According to Trooper Larsen, the accident is still under investigation but alcohol is believed to have been a factor in the accident.
