http://www.9news.com/news/top-article.aspx?storyid=86924 WELD COUNTY - A firefighter was killed Saturday morning when the fire engine he was driving crashed and rolled. The Ault-Pierce Fire Protection District says the fire engine was en route to render aid to a sick and injured caller in Ault when the fire truck was involved in a crash. The Colorado State Patrol says the firefighter, who has been identified as 33-year-old Capt. Shane Stewart, was driving the truck at the time of the crash. They say Stewart was driving just south of Pierce, Colo., at 6:20 a.m. on southbound Weld County Road 33 when he ran off the left side of the road, overcorrected and went off the right side of the road. Troopers say that's when the truck rolled onto its roof, ejecting and killing the driver. According to the state patrol, there was no one else on the truck at the time. "In my 20 years experience as a law enforcement officer, I have never had occasion to see a fire truck involved in a crash like this," said Paul Matzke, captain of the Colorado State Patrol for Weld County. Fire officials say Stewart had been a volunteer member with the Ault-Pierce Fire Department since August 2004. His brother and father are also volunteers with the 21-member department. Stewart was employed with the Colorado Department of Transportation and was married with two young children. "In these smaller towns, the departments are usually made up of mostly volunteers," said Matzke. "So, it's a close community. These folks all know each other and I'm sure this is a real tragedy for all involved in this community." A vigil has been scheduled for 7 p.m. Saturday at the Pierce Fire Station. Prayers with family and crew.
