PHOENIX - Rob Dollar’s family say he was full of life. An avid cyclist, he loved the challenges that came from cycling. Whether it was pushing through hills and steep climbs, he took on whatever the road gave him.

Sadly, he lost his life Sunday morning cycling down South Mountain on Summit Trail Road. According to Phoenix police, he was struck by a car driven by 19-year-old Annaleah Dominguez, who crossed the double yellow line attempting to pass another bicyclist.

Police say Dominguez had shown signs of impairment and admitted to drinking and ingesting marijuana sometime before the collision. Officers later discovered marijuana just outside the car that a passenger had thrown out.
