A freight train collided with a sport utility vehicle near the Kansas state line Thursday, killing six migrant workers in the SUV, police said.

Another person in the SUV suffered serious injuries in the collision at a spot where tracks cross a county road that cuts through farm fields outside Granada, the Colorado State Patrol said. The person's condition was not immediately available.

No one aboard the BNSF Railway train was hurt, authorities said.

Five victims died at the scene, and the sixth died after being flown to a Denver hospital, the patrol said.

Prowers County Coroner Joe Giadone said the dead included three women in their 20s, a boy 12 to 14 years old and a 36-year-old man, and that all died of massive trauma. The sixth victim was a male whose age was not immediately known.

The hometowns of the migrants were also not yet known, Giadone said, but the SUV had Texas plates and he found identification papers from Texas and Montana.

Granada, a town of 640 people, is about 170 miles southeast of Denver. BNSF spokeswoman Lena Kent said the crossing where the crash occurred is marked by signs but no lights or gates.
