Sheriff: Disgruntled ex-worker killed 5, then himself in Orlando

The 45-year-old male suspect armed with handgun and knife appears to have shot five victims, Sheriff Jerry Demings said. There's no indication that he had ties to "any subversive type organization" or terrorist group, Demings said, and authorities believe the shooting was "likely a workplace violence incident".

Shelley Adams's sister Sheila McIntrye works for the company and was in the toilet when shots rang out. "My boss is dead".

State and federal law enforcement officers converged on the industrial park in Orlando shortly after 8 a.m. after a woman ran out and called 911 from a tile business across the street, said Yamaris Gomez, that store's owner.

That woman had been hired after Neumann was sacked in April, so he probably did not recognize her and knew she was not a former co-worker, Deming said.

He says about 12 people were at the company and seven people survived. He said the attack shows why people need to alert authorities if they learn of anything that could lead to violence. Several Orange County Fire and Rescue vehicles were seen leaving the scene afterward.

Fiamma calls itself one of the largest manufacturers of awnings for camper vans, motor coaches and sport utility vehicles.

Florida Gov. Rick Scott said he'd been briefed on the incident and remained in touch with law enforcement.

Nearly a year ago, an attack at a gay nightclub in Orlando left 49 people dead, in the deadliest mass shooting in modern USA history.

The sheriff's office said victim advocates are standing by at Family Unification Center at Full Sail University 3535 North Forsyth Rd. "My boss is dead".

Five people have been killed in a shooting at a workplace in Orlando, Florida.

"It is a sad day for us here once again in Orange County", Demings said. No further details were immediately available.

On its officials twitter account Monday morning, the Orange County Sheriff's Office said the "situation" has been contained. Officials said they would provide an update as soon as the "info is accurate".
