GREELEY, Colo. (AP) — A 58-year-old man has been charged in the death of a Colorado State Patrol trooper who was struck and killed by a car during last month’s blizzard.

The Weld County District Attorney’s Office on Thursday announced that John G. Carpenter, of Centennial, was charged with failure to exercise due care when approaching a stationary vehicle that resulted in death and careless driving causing death.

Carpenter said in an interview that he was scared and hadn’t been contacted by anyone for his side of the story. He couldn’t comment further until he meets his attorney, Dan Carr.

Carpenter is to appear in court May 29 at Greeley.

Authorities say Carpenter’s car hit Cpl. Daniel Groves on March 13 as the trooper was helping a driver who had slid off Interstate 76.
