ORLANDO, Fla. — Update -- 2:16 p.m. ET
Orange County Sheriff Jerry Demings during a news conference Monday afternoon identified the gunman and five victims who were killed earlier in the day during a mass shooting at a business in an industrial area near Orlando.
Demings said John Robert Neumann Jr., 45, fatally shot Robert Snyder, 69, Kevin Lawson, 46, Brenda Montanez-Crespo, 44, Kevin Clark, 53, and Jeffrey Roberts, 57, before turning the gun on himself shortly after 8 a.m. at Fiamma Inc., a manufacturer of RV awnings, on Forsyth Road near Hanging Moss Road.
Investigators said Neumann was armed with a handgun, a large hunting knife and a smaller knife. The gunman reloaded at least once during the shooting, deputies said.
Demings said Neumann appeared to single out people and had a "negative relationship" with at least one victim. He warned a young woman who was a temporary employee, to run.
Neumann lived alone and had no family in the area, Demings said. The gunman was a veteran in the U.S. Army and was honorably discharged in 1999, he said.
Original story -- A disgruntled employee fired from a Florida business in April returned to his former workplace Monday and fatally shot five people before turning the gun on himself, Orange County sheriff's deputies said.
The shooting is not believed to be a case of terrorism, Sheriff Jerry Demings said.
Deputies responded to the shooting at the Fiamma Inc building on Forsyth Road in Orlando around 8 a.m. The company manufactures accessories for RVs.
The situation was contained by 9:15 a.m., deputies said.
Investigators said a 45-year-old disgruntled employee armed with a handgun and a knife fatally shot three men and one woman at the business.
Demings said the man shot a fifth person, a man, who later died at Orlando Regional Medical Center.
"Our hearts and prayers go out to the families of the victims this morning," Demings said.
Authorities did not immediately identify the suspected shooter or the victims.
Shelley Adams told WFTV that her sister, Sheila McIntyre, called her from the building where the shooting took place as it was ongoing. McIntyre works at the Fiamma Inc. building on Forsyth Road.
"She just kept saying, 'I'm OK; I'm OK,'" Adams said. "She just kept saying, 'My boss is dead; my boss is dead.'"
Adams said McIntyre was in a bathroom and saw someone on the floor when she got out.
"We're just going to embrace her and not leave her alone and just be there as a family," Adams said. "It's unbelievable that it could happen in a small business."
Florida Gov. Rick Scott called the shooting "tragic" in a statement Monday morning and said he was being briefed by law enforcement officials.
"Over the past year, the Orlando community has been challenged like never before," he said. "I ask all Floridians to pray for the families impacted by this senseless act of violence."
The shooting remains under investigation.
