ESTES PARK, Colo. — A woman died Tuesday, roughly 15 hours after being pulled from the Big Thompson River near Estes Park.

Bystanders performed CPR on the woman at the river, David Moore, public information officer from the Larimer County Sheriff’s Office (LCSO), told 9Wants to Know. Those rescue efforts continued on the way to the hospital.

“Unfortunately, she passed away today,” Moore said. “LCSO investigators are working to determine how and why she was in the river.”

Moore said the sheriff’s department is working with the Larimer County Coroner to determine if foul play is suspected. He said right now it’s too early to tell. 

Debbie Reisdorff, a deputy coroner within the Larimer County Coroner’s office, confirmed the woman died approximately 15 hours after arriving at a hospital. Reisdorff did not identify the dead woman. She said an autopsy will be performed tomorrow.

It is possible the unidentified woman fell into the river. Moore said similar incidents with rafters, tubers, and swimmers have happened in the past. He will only know for sure after the investigation wraps up.

“At least a few times a year in unincorporated Larimer County, unfortunately, people are pulled into the rivers and succumb to injuries,” Moore said. “I wouldn’t say it’s a common occurrence.”

Moore urged anyone who may have information in the case to call the LCSO at 970-416-1985.
