Montgomery was taken to Banner Desert Medical Center where he later died, according to the Arizona Department of Public Safety.
The department said Montgomery appears to have “struck a wall” while exiting the University ramp, which has been closed for investigation.
Rest In Peace Officer Montgomery.

“Our thoughts and prayers are with his family,” the tweet said.
Gov. Doug Ducey ordered flags at all state buildings be lowered to half-staff Friday to honor Montgomery.
“He put his life on the line to protect others, and we are grateful for his bravery, sacrifice and service. Our prayers are with his wife, four children, loved ones and the ASU Police Department during this difficult time,” Ducey said in a tweet.
