A deadly crash trapped as many as 10,000 people in Grand Lake late Thursday night into Friday morning.
Hordes of visitors had descended upon the small mountain town to view the community's popular Fourth of July fireworks show. The crash happened just after the show ended.
According to sister station KCNC, a truck hit a couple and three of their eight children as they were walking along Highway 34 after the show. Fifty-year-old Greg Westley of Estes Park was killed. His wife and the three children were flown to a hospital in Denver for treatment. The youngest of the injured children is 3 years old.
The crash shut down Highway 34 for hours, forcing thousands to remain in Grand Lake until the scene was cleared. Grand Lake is nestled against the west side of Rocky Mountain National Park, and there are few options besides the highway for getting in and out of town.
The 33-year-old driver of the truck, identified as Lucas Ackerman of Grand Lake, has been taken into custody. Alcohol is suspected to be a factor in the crash.
