The Maricopa County Sheriff's Office says 21-year-old Katelyn M. Conrad was rappelling (also known as abseiling) in Coon Bluff, a popular recreation area near the Salt River, on Saturday morning when the accident occurred.

Sheriff's Office spokesman Chris Hegstrom told that Conrad would be unresponsive to revive her. Despite life-saving efforts by deputies, Conrad would be pronounced dead.

Authorities say Conrad was part of a group of 20 to 25 climbers from ASU.

'There was only 1 or 2 people actually with her at the time of the fall, everybody else heard screams and came to the scene,' Sgt. Aaron Flowers with the Maricopa County Sheriff's Department told Fox 10 Phoenix.

They also say Conrad, who was from nearby Gilbert, was the daughter of a Phoenix police lieutenant.

Investigators are looking into the cause but say it appears to be accidental.
