George Zimmerman, the man who killed unarmed Miami teenager Trayvon Martin, has allegedly threatened to kill again.

Zimmerman was involved in a road-rage incident near Orlando and allegedly asked another driver, "Do you know who I am?," undoubtedly referring to his known status as a someone who taken another person's life. He then threatened to kill the man.

According to USA Today, a man in Lake Mary, Florida, called police after a driver, later identified as Zimmerman, pulled up next to him in a truck and shouted, "Why are you pointing a finger at me?"

The man recognized the driver as Zimmerman, and claimed Zimmerman followed him into a parking lot.

At some point Zimmerman allegedly asked, "Do you know who I am?" before telling the man, "I'll (expletive) kill you."

The man called 911, but Zimmerman drove away before police arrived.

The man then saw Zimmerman two days later, allegedly waiting for him outside his workplace, but later refused to press charges.

Zimmerman has been accused of other violent acts since being acquitted on charges of killing Martin only to have those charges dropped once the victims refused to press charges. In one he was accused of assaulting the father of his ex-wife. In another he was accused of assaulting a pregnant girlfriend.
