It is sad...but these things happen.

I had a friend pass in this same manner, two years ago. He was eastbond on I-90, crossing Mercer Island, there in the Seattle area, when he had his attack. Lucky for traffic that he didn't have his cruise control set. He was hauling 11,500 gallons of gas when the truck left the road. No spill, no injuries, except for the passing of one James Knox.... a very mellow guy. Like this guy, Jim was gone before the truck came to a stop.
