DENVER (CBS4) - A driver was sentenced on Wednesday for causing a crash which killed a Colorado State Patrol trooper. Cpl. Daniel Groves was helping another driver on Interstate 76 when John Carpenter hit him.

A judge sentenced Carpenter to 90 days in jail and 850 hours of community service.

The crash happened in the middle of the so-called bomb cyclone blizzard last March between Brighton and Fort Morgan.

Carpenter, 58, pleaded guilty in October to careless driving resulting in death and failing to exercise caution while approaching a stationary vehicle, resulting in death.
