A recently fired worker from an awning company in Florida followed through with a plan to kill his former colleagues, singling out five and fatally shooting them in the head before taking his own life, authorities said.
John Robert Neumann Jr., 45, shot and killed himself at the sound of approaching sirens Monday. He did not appear to belong to any type of subversive or terrorist organization, Orange County Sheriff Jerry Demings said.
"My experience tells me that this individual made deliberate thought to do what he did today. He had a plan of action," said the sheriff, who wouldn't say why Neumann was fired in April.
Demings said Neumann had a "negative relationship" with at least one of his former co-workers in Orlando, and he singled out the former colleagues who were shot.
The shooting began after Neumann slipped through a rear door into the cavernous Fiamma Inc. factory, an area larger than two football fields where awnings are stitched together for recreational vehicles. He paused at least once to reload. Seven other workers were inside at the time but were unharmed.
State and federal law enforcement officers converged on the industrial park 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.
"All she kept saying was he was holding a gun and told her to get out," Gomez said.
That woman had been hired after Neumann was fired in April, so he probably did not recognize her and knew she was not a former co-worker, Deming said.
Deming said investigators were looking through any social media postings for clues. Neumann was honorably discharged from the U.S. Army in 1999 and did not have a concealed weapons permit, the sheriff said.
The dead were identified as Robert Snyder, 69; Brenda Montanez-Crespo, 44; Kevin Clark, 53; Jeffrey Roberts, 57; and Kevin Lawson, 46.
Authorities had confronted Neumann once before at the factory, when he was accused of battering a co-worker in June 2014. But no charges were filed after both men were interviewed, and that co-worker was not among Monday's victims, the sheriff said.
In a 2014 incident report, Neumann's co-worker said Neumann punched him in the back of the head when he approached, knocking him to the ground. But the co-worker later changed his story, saying Neumann had chased him and then hit him on the back of the head.
The co-worker, who had no visible injuries, stated "he had problems in the past with John but thought they were resolved," the sheriff's office incident report said.
Neumann had a record of minor crimes, none violent, dating back more than 20 years. Most involved traffic violations: driving under the influence, driving with a suspended license, giving a deputy a false name and leaving the scene of a hit-and-run involving property damage.
Searching for a motive, deputies cordoned off a trailer park in Maitland, where Neumann lived alone in a mobile home on a busy road next to a funeral home, a used car lot and a dog-grooming business. Like the awning factory, it's far from Orlando's famous theme parks.
Arnie Boyd, who lives in the same trailer park, said Neumann was not particularly social. "Every once in a while, he would ride his bike around and that's it," Boyd said. "We would speak only once in a while."
Authorities had no reports of any specific threats the gunman made to people at the company or anyone else, but that's why people need to alert authorities whenever they learn of anything that could lead to violence, said Special Agent Danny Banks of the Florida Department of Law Enforcement.
U.S. Sen. Bill Nelson noted that next Monday will mark a year since the worst mass shooting in modern U.S. history at a gay nightclub in Orlando. The attack at the Pulse club killed 49 people and wounded dozens more.
"The city of Orlando, which is still healing from the Pulse massacre, has seen too much violence this past year," the Florida Democrat said in a statement.
