TUCSON (KGUN9-TV) - The death of a University of Arizona student is shedding light on the issue of speeding along the popular Catalina Highway.
Spencer Repp, 19, is the latest motorcycle crash victim on Mount Lemmon.
According to friends, Repp loved taking his motorcycle up the mountain whenever he wasn't in class studying for his business degree.
"He took frequent trips up there, everyone always said be careful, don't want anything to happen up there... It's beautiful place," said Ryan Locke, a friend and fraternity brother.
Deputy Tom Peine with the Pima County Sheriff's Department says Repp appears to have been speeding when before he lost control and flipped over a guardrail.
9OYS's Alexis Fernandez asked: "When you heard what happened, what was your initial reaction?
"Disbelief, couldn't believe it," Locke responded.
Peine says Repp was conscious and talking when rescuers arrived at the scene.
"Was alert, lucid, spoke to rescuers -- provided information as needed," he said.
He died hours later at the hospital as a result of his injuries.
Deputies say speeding on the curving Catalina Highway happens all too often.
"They take this risky behavior that not only endangers themselves but others because if a motorcycle crashes, there can be other people around," said Peine.
"They will come up, whip around you and not even know if someone's in front of you at all, just scares you," said one driver on Mount Lemmon.
Repp was wearing a full-faced helmet with a camera mount on it. No camera was found at the scene.
