A homeless man who police say was incoherent when he was apprehended is facing armed robbery charges for multiple alleged attacks on cyclists in the Crandon Marina area Thursday.
Miami-Dade Police said Stephen Mangrum, 43, struck one cyclist with a diving weight wrapped in a T-shirt, knocking him down. Mangrum then allegedly demanded property. When told the cyclist didn’t have anything else, Mangrum allegedly took the bike and rode off with it.
A short time later, police said, two other victims reported an attack, and an officer spotted Mangrum, still riding the bicycle. The officer took Mangrum into custody and the victims were able to identify Mangrum, the report said.
A detective attempted to question Mangrum, but said “the defendant was speaking incoherently and advised he had built pyramids and wrote the Bible.”
Mangrum remains detained on $40,500 bond on charges of armed robbery, attempted armed robbery, aggravated battery, and resisting arrest without violence. No plea has yet been entered.
