HIALEAH, Fla. — The gunman who went on a shooting rampage at his South Florida apartment building, killing six people, was a lonely man who spoke about having pent up anger, those who knew him said Sunday.
Pedro Vargas, 42, lived on the fourth floor of a barren, concrete apartment complex in the Miami suburb of Hialeah with his elderly mother. He rarely spoke with others there, and confided to a man who worked out at the same gym that he liked to work out his anger by lifting weights and trying to get big.
"He'd just say this was the only thing that would keep him normal, pulling out all the anger in the gym," Jorge Bagos told The Associated Press.
Bagos said the gunman expressed frustration over bad experiences with women and losing all his hair from using steroids.
