The 43-year-old gunman who set fire to his apartment in suburban Miami and then fatally shot six people in and around the building had given authorities no reason to believe anything was amiss until Friday night, police said Saturday.
“Nobody seems to know why he acted the way he acted,” Hialeah Police Department Spokesman Carl Zogby told reporters about Pedro Vargas.
Police were looking into the possibility that Vargas — described by some as a “quiet” man — may have had a dispute with the building managers, who were among his victims, Zogby said.
But that had not been established. An initial check indicated that Vargas had no criminal history and no history of irrational behavior. “We don’t have an explanation,” Zogby said.
