A Colorado state patrol officer who was hit by a car during a winter storm while responding to an accident has died.
The Colorado State Patrol says Corporal Daniel Groves was outside his patrol car along Interstate 76 northeast of Denver on Wednesday when a driver lost control and hit him.
Officials say Groves was helping another driver who had slid off the highway. The State Patrol said Groves was taken to a hospital but died there of his injuries. Groves was 52 and had worked for the agency for nearly 12 years.
The crash is being investigated. The statement said high speed in poor driving conditions may be a factor.
