Dezjon Hamilton, a 21-year-old motorcyclist, was intentionally run down in Chandler, Arizona, following a road rage incident. His family has taken him off life support and he is brain dead with no brain function. The incident occurred after a confrontation with Gustavo Elias, 29, who admitted to drinking around 12 beers and using cocaine before driving. Hamilton was hit along a Chandler roadway after he "excessively revved" his engine in front of Elias. The family is urging drivers to slow down, share the road and respect motorcyclists.
