Employees at a Ford dealership in the San Francisco Bay Area were apparently concerned about a colleague who had just been fired because of his 'history with guns,' less than 10 minutes before he shot and killed two managers and then himself.

Police received multiple 911 calls at about 6.03pm Tuesday evening after the shooter opened fire in the service department of the dealership in Morgan Hill, southeast of San Jose.

Doug MacGlashan, who was hired by the dealership for the day to train employees on new software, told KRON-TV that a parts department representative who had been terminated that day apparently went outside, got two guns and returned to shoot the two employees.

The service and parts director 'had just fired a parts rep that he had said he was going to fire earlier in the day. And I guess the parts rep went outside, got a gun, went into the service and parts director's office and shot him', MacGlashan said.

Macglashan said the suspect wouldn't leave the dealership after he was fired, and the manager who let him go expressed concern.

'He said "I just fired him, he won't leave the premises. Should I be worried, what should I do?"' MacGlashan told NBC Bay Area. 'So they were wondering should they call authorities. At that point, somebody asked, "Should we be worried?" Somebody said, "Yeah, he's got a history with guns." Not 10 minutes later, we heard gunshots.'

The man also killed the parts manager, he said.

As of early Wednesday morning, police have not released the name of the gunman or his victims.

Morgan Hill Police Department took to Facebook and wrote: 'Officers responded and arrived on scene at 6.07pm. Upon their arrival at Ford Store officers located a deceased male subject on the ground with what appeared to be a self-inflicted gunshot wound.

'In his hand was a firearm, a handgun,' police Sgt. Bill Norman said at a news conference on Tuesday.

'Officers were directed by Ford Store employees inside the Ford Store building where two Ford store employees with apparent gun shot wounds were on the floor. Medical aide responded and both victims were pronounced deceased at the scene.'

Employee Jordan Valdez said the shooter, a man in his 60s or 70s, had worked there for a while. He added that two other young employees were also let go earlier that day.

'He was a very quiet individual. Just kind of minded his own business, very humble, to himself. He did his job,' Valdez said.

Police officers searched a home in San Jose late Tuesday evening, believed to be the residence of the suspected gunman, KPIX reported.

Police said: 'The Ford Store building (seen above) has been cleared and secured. There is no threat to the public'

The police Facebook post added: 'The Ford Store building has been cleared and secured. There is no threat to the public.

'Morgan Hill Police is conducting and thorough and in-depth investigation and will be on scene for some time.

'We ask for the public's patience as Condit Road continues to remain closed from Dunne to Diana. All residents in the area have access to their homes through other means. The only business currently impacted is La Quinta Hotel and its guests.

'The City of Morgan Hill and the Morgan Hill police Department offer our sincere condolences to the families of the victims in this tragic incident.'

Video and photos showed police cars from several agencies swarming the dealership and employees embracing as they left the property.
