A single father-of-two was one of five victims who were tragically killed on Monday when a disgruntled ex-employee barged into his old office and shot his former co-workers dead before turning the gun on himself.

Kevin Clark was gunned down by 45-year-old Army veteran John Robert Neumann Jr who went on a deadly rampage at the Orlando offices of RV awning company Fiamma Inc around 8am on Monday. 

Clark had just celebrated his son’s graduation from Lyman High School with a party the day before he died.

‘We had a large family get-together just yesterday,’ his brother Chris Clark told the Orlando Sentinel.

Friends of Clark started a GoFundMe page for his family shortly after the attack.

The organizers revealed his 14-year-old cheerleader daughter Delaney and 18-year-old football star son Gavin are now orphans.

Neumann also shot and killed 69-year-old Robert Snyder, 44-year-old Brenda Montañez-Crespo, 57-year-old Jeffrey Roberts and 46-year-old Kevin Lawson. 

Lawson was a married father-of-four daughters and had two granddaughters.

He started working for Fiamma in 2014. He worked in shipping and receiving at the company and lived in Longwood, according to his Facebook page.

Snyder was an avid pool player at Turtle Bay Bar in Orlando. His friends gathered Monday night to remember the skilled billiard player.

The bar owner told News 6 that Snyder played pool there every Thursday in a pool league for 25 years.

Snyder’s Orlando neighbor Tiffany Almany told the station that he was only a year from retiring as a manager from Fiamma and had several adult children. 

Roberts worked as a sales manager at Fiamma Inc and had just started in January.

Montañez-Crespo, who leaves behind daughters and a granddaughter, worked at the front desk of the business.

Demings quickly ruled out any link to terror in the wakes of recent attacks. He said Neumann lived alone and didn’t have any family in the area. 

According to Army records, he was honorably discharged in 1999. Investigators are ‘trying to understand as much about [Neumann] as we can,’ Demings said.   

One of the co-workers was a sales manager while the others were former co-workers.  

Clark had only started working at Fiamma a short time before he died. 

His brother, Chris Clark, told the Sentinel that his sibling had a passion for photography and ran his own business on the side. 

‘He shot weddings and team pictures,’ Chris Clark said. ‘Almost every weekend he was somewhere shooting Little League teams or Pop Warner.’

Kevin Clark is also survived by his twin sister. 

Demings said his department received a 911 call at 8.03am about an active shooter situation at the company, which is located in an industrial park. 

Officers were on the scene within two minutes, and found Neumann dead – in addition to three male victims and one female victim. 

Another male victim was taken to Orlando Regional Medical Center where he was later pronounced dead. 

Most of the victims were shot in the head and some were shot multiple times.

Witnesses said that the shooter arrived at the office armed with a handgun and a knife, but Demings said there’s no evidence to indicate the shooter used the knife during the attack. Demings said it appears that Neumann reloaded his semi-automatic pistol at least once during the shooting.  

After shooting five of his co-workers, the shooter turned the gun on himself and committed suicide.   

Seven other people were at Fiamma at the time and survived. There was also another witness who was a vendor. 

They were taken to another location to be interviewed by police. 

Neumann had a slew of arrests for minor crimes including drug possession and DUI. He is seen in an array of mugshots from 1995 to his most recent in 2010

One of the witnesses, a woman who worked as a temp, said that when Neumann arrived at the office, he pointed a gun at her and told her to get out – suggesting that he was only targeting people he had worked with during his time at Fiamma. 

There weren’t any security cameras running inside the business, but there was one outside by the rear entrance where Neumann is believed to have shot the first victim, Demings said.

Neumann had a minor criminal history including arrests for marijuana possession, DUI and misdemeanor battery.

Demings said officers were called to Fiamma three years ago, when the shooter allegedly battered a co-worker.

However, no charges were filed at the time. 

Demings also said there was nothing to indicate that the shooting was related to terrorism, and that it’s likely a ‘workplace violence incident’.

Shelley Adams said her sister, Sheila McIntyre, called her from Fiamma’s bathroom during the shooting and was very upset.

Adams said she kept repeating: ‘My boss is dead. My boss is dead.’

McIntyre was not injured. Adams described the company as a small business with around 10 employees.  

The FBI joint terrorism task force sent an official to the scene to aide in the investigation.  

Earlier on Monday, authorities closed the road near the scene and urged motorists to ‘use caution’.
