Mount Vernon, WA: Truck driver suffered medical incident before huge I-5 pileup on Saturday, July 18th 2015

The driver of a dump truck that crashed on Interstate 5 in Mount Vernon, triggering a 28-vehicle pileup that injured six people, suffered a medical condition that caused him to lose control of his rig, the Washington State Patrol said Sunday.The dump truck was carrying a 80,000-pound load of clay and gravel when it crossed the I-5 median Saturday, plowing into oncoming traffic that was stopped while police investigated an earlier fatal shooting, authorities said.Twenty-eight vehicles were involved in the collision, and traffic backed up for miles as lanes were closed for hours in both directions.Six people were injured, in addition to the truck driver.A 21-year-old Liberty Lake man who was driving a 2003 Chevy Trailblazer was airlifted to Harborview Medical Center in Seattle, where he is listed in critical condition.
The truck driver, a 60-year-old Everson man, had a broken arm and chest injuries. He sustained a "medical situation" that incapacitated him just before the crash, the State Patrol said in an accident memo issued Sunday. He was airlifted to Harborview Medical Center and is listed in serious condition.Authorities say the truck was traveling south when it broke through a cable barrier in the median into the northbound lanes."It was bumper-to-bumper traffic, and then ... it was like the semi just flew over the whole median and there was dirt everywhere," witness Bobby Grace told KOMO-TV. "So much dirt, it was like a sand storm. It was astonishing."Before the crash, traffic was slowed for the shooting investigation. Troopers were called to the area and found two men in their 20s dead inside a car just after 3 a.m. A man in the backseat of the car managed to jump into the front seat to steer the car to the shoulder.The passenger called police and told investigators that a pickup pulled up next to the car and someone inside opened fire.
