Three children were among the five family members killed when an Amtrak train collided with their minivan Sunday morning as they headed to church.
One child survived the crash. She was flown to the Children's Hospital in critical condition, according to CSP.
Investigators say the crash happened on Las Animas County Road 32, around three miles north of Trinidad. 9NEWS sister station KOAA-TV reports the parents who died were Christina and Steve Miller.
Their children, Abigail, Kathryn and Ellianna also passed away. Four-year-old Heidi Miller was the only survivor.
The minivan was headed northbound on CR 32 when it failed to yield to an Amtrak train that was headed westbound, according to CSP. The front of the train collided with the right side of the 2005 Chrysler Town & Country, pushing it westbound on the tracks until the train was able to stop.
An Amtrak spokesperson says there were 286 passengers aboard at the time. No passengers or crew were hurt.
The train was held at the location of the crash for hours, but as of 5:25 p.m. is back on the move. It is traveling from Chicago toward Los Angeles on the Southwest Chief Line.
According to a statement from Amtrak, the train was damaged and crews had to make repairs before it could travel again.
CSP says alcohol and drug use are not suspected in the crash. Investigators believe failing to yield to the train is the main factor behind the five deaths.
Contrary to earlier reports, CSP says the vehicle was not believed to have been stopped in the tracks.
