PHOENIX -- Authorities say a suspect has been arrested in the fatal collision of a dirt bike and an all-terrain vehicle in north Phoenix.
Phoenix police said 48-year-old Gregg Creevy has been booked into jail on suspicion of leaving the scene of a fatal collision and tampering with evidence.
The accident occurred Dec. 17 in a desert area of North 57th Street.
Police say the rider of the motorcycle -- 20-year-old Frisco Davidson-Spurs Yankolovich -- later died of his injuries at a hospital.
He was wearing a helmet at the time of the crash.
Witnesses said the rider of the ATV stopped and looked at the victim, then left the scene.
Police shared information gathered from witness accounts with the community to help find Creevy. It's unclear if he has a lawyer.
