BOULDER COUNTY, Colo. -- A truck flipped over into Boulder Creek near Sugarloaf Road in Boulder Canyon Saturday.
According to the Boulder County Sheriff's Office, a call about a crash at Highway 119 and Sugarloaf Road came in around 4:45 p.m.
A father was traveling with his two daughters when a car in front of him stopped suddenly because of a bear, said deputies. He ended up rear-ending the car, which then sent his vehicle into the creek.
The father and one of the daughters managed to get the opposite side of the bank, but a 13-year-old girl was swept downstream by the rushing waters.
More than 100 responders were on scene to rescue the girl from the waters.
A diver eventually recovered her behind Boulder High School.
Boulder County Sheriff Joe Pelle confirmed to FOX31 Denver that the girl was recovered unconscious and immediately transported to Boulder Community Hospital at 1100 Balsom Ave.
Deputies said rescue crews had a visual of the girl the entire time, but they couldn't get to her.
She drifted more than six miles downstream before she was recovered at about 6:07 p.m.
At about 8:45 p.m., a Boulder County sheriff confirmed that the 13-year-old victim has passed away as a result of her injuries.
