GREELEY, Colo. — A good Samaritan was seriously injured after stopping to help people involved in a deadly head-on collision on Thursday night, the Greeley Police Department said.

The crash happened about 9:15 p.m. near 75Avenue on the Highway 34 Bypass when witnesses reported a blue Subaru traveling westbound lost control because of icy road conditions, police said.

The driver slid off the highway, went through the median and into the eastbound lanes, crashing head-on with a Nissan.

Police said a woman parked her vehicle on the shoulder to check on the drivers and passengers in the vehicles involved in the crash. She was hit by a vehicle as she was crossing the road on foot.

Another vehicle traveling eastbound then lost control and struck the vehicle of the good Samaritan, police said.

One of the passengers in a vehicle involved in the head-on collision was found unresponsive by officers and was taken to North Colorado Medical Center but was later pronounced dead.

The woman who stopped to help was taken to North Colorado Medical Center in serious condition and is undergoing surgery for multiple injuries, police said.

Police did not say if there were any other injuries. Drugs and/or alcohol are not suspected as contributing factors to the accident.

The name, age and gender of the person who died will be released after notification of next of kin by the Weld County Coroner’s Office.
