Six people, including a gunman, were fatally shot Monday morning in an episode of workplace violence in an industrial area near Orlando, Orange County Sheriff Jerry Demings said.
Deputies were called to Fiamma Inc., a manufacturer of RV awnings, shortly after 8 a.m. on Forsyth Road near Hanging Moss Road after reports of an active shooter, Demings said.
Investigators said a 45-year-old disgruntled employee armed with a handgun and a knife fatally shot three males and one female at the business.
Deputies said the man shot a fifth person, a male victim, who was taken to Orlando Regional Medical Center, where he died. The gunman then shot himself.
Demings said the man, whose identity wasn't released, was a former employee of the business who was fired in April.
The sheriff said the gunman had a criminal history that was "minor in nature," including marijuana possession, driving under the influence and battery charges.
Orange County detectives are interviewing seven survivors.
