Police are investigating after a woman was killed after being hit and dragged by a light rail train in Denver today.

It happened shortly after 1 p.m. near Welton and 24th streets, across from Sonny Lawson Park.

About an hour after the incident, Denver Police spokesman Sonny Jackson confirmed a white woman in her mid 20s had died from her injuries. Her name was not released.

Ryan Collins, a construction worker who was working on a nearby building, witnessed the incident.

He said he noticed a woman staggering around, as if intoxicated. She stood in front of the train, on the tracks, until the train came to a stop for her.

“She stood in the middle of the tracks and waved down the light rail,” Jackson said. Jackson said it wasn’t clear if the woman was intoxicated.

Collins said the woman then walked around the side of the train as if she was going to board it, but there wasn’t a stop there and the train took off without opening its doors.

That’s when, Collins said, the woman got caught up underneath the light rail.

“We saw the train move, and she started tumbling around,” Collins said, visibly shaken by the incident.

Jackson said the woman was dragged about 20 feet.

Collins, along with several other people, ran toward the woman. The train had come to a stop at that point and the woman was limp, he said.

The driver of the light rail got out of the train and ran toward the woman, Collins said, but people told the driver not to touch her or move her.

“Her legs were under it, she got dragged under it,” Collins said.

Paramedics arrived quickly, Collins said, and they pulled her out from under the train and started performing CPR on the sidewalk. After a few seconds, they put her in an ambulance and rushed her away from the scene.

“She was messed up,” Collins said. “Her eyes were shut.”

Collins said when she was dragged, the woman did not scream or cry out. By the time he got to her, she seemed to be unconscious.

A hat and a woman’s handbag were lying in the pavement near the three-car D-line light rail train.

Denver police homicide investigators and RTD investigators were on scene looking into the incident.
