Zackary Standley was arrested at the scene of the crash and later lodged at the Clackamas County Jail on one count of reckless driving, two counts of recklessly endangering another person, and two counts of fourth-degree assault.

The 11:19 a.m. Friday crash completely stopped southbound traffic. Motorists had turned off their cars and were walking around on the freeway as emergency personnel assisted the crash victims. Wilsonville’s side roads, especially S.W. Parkway Avenue and S.W. Wilsonville Road were backed up for more than two hours as freeway traffic was diverted through the city.

Soon after the crash, one of the first bystanders on scene was off-duty Tualatin Valley Fire and Rescue captain Leonard Damian, who had been travelling northbound on Interstate 5.

“Captain Damian, along with other good Samaritans, helped stabilize the trapped victims,” said Tualatin Valley spokesperson Cassandra Ulven. “Captain Damian also requested resources from dispatch, including LifeFlight.”

Firefighters arrived to find two vehicles: a Toyota 4-Runner, which had gone into the median and rolled several times before resting on its side near barrier cables. Standley was driving a 1994 Acura Integra, which had gone off the freeway on the right shoulder, driven through hedges and stopped near Boones Ferry Road.

The Toyota was driven by 63-year-old Irene Frost of Salem. She was struck from behind at a high rate of speed by Standley’s car, which caused the 4-Runner to roll several times, said Worthy, adding that witnesses saw Standley following other vehicles too closely.

“Standley reportedly lost control of the Acura just before colliding with the rear end of the Toyota 4-Runner,” Worthy said.

Once firefighters arrived, they immediately began assessing the medical condition of the two trapped occupants in the Toyota 4-Runner, said Ulven.

“After stabilizing the vehicle, firefighters continued to provide medical care to the trapped victims while another crew of firefighters used heavy equipment to cut and pry portions of the vehicle’s roof,” she said.

Jodi Hunter, Frost’s 38-year-old daughter, was a passenger in the 4-Runner. After being extricated from the vehicle, she was flown by LifeFlight to Legacy Emanuel Hospital in Portland.

A total of 19 fire personnel responded to this incident, as well as Oregon State Police, Clackamas County Sheriff’s Office and ODOT.

Firefighters and police officers contended with a number of hazards on scene.

One of those included passersby who slowed to take pictures of the scene with their cell phones, endangering emergency crews and other drivers, said Ulven.

One lane remained closed until about 2:30 p.m. while officers investigated the crash.

Coincidentally, some of the firefighters who responded to this call had just finished a training exercise which involved crushed cars to simulate a crash.
