A white gunman identified as, Nathan Allen, stole a workman’s truck and crashed it into a home, exited the truck and walked away before shooting a man and a woman among the bystanders who came to check on him – Both victims were black

Allen, 28, is believed to have deliberately murdered David Green, 58, a retired Massachusetts State Trooper and 60-year-old Air Force veteran Ramona Cooper, ‘because of the color of their skin’

Suffolk DA, Rachel Rollins, said the case remained under investigation as a hate crime.

Rollins noted that other people in the neighborhood who were not Black had approached Allen out of concern he’d been in an accident. Allen walked by “several other people” who were not of color, and shot two innocent handpicked people

He was ‘interacting with multiple individuals and choosing only to shoot and kill the two black people he encountered,’ Rollins said

Police later found ‘troubling’ white supremacy rhetoric and statements written by the shooter, which whites being ‘apex predators’

One of the responding officers fatally shot Allan during the encounter

Allen was married, employed, had a PhD, with no criminal history and before Saturday’s encounter, wasn’t on the radar of law enforcement

A gunman has shot two people in suburban Boston on Saturday before being shot by police, in an incident that saw a plumbing truck crash into the side of a house. The gunman who cops said is a ‘white supremacist’ who considered himself an ‘apex predator’ crashed into the Winthrop, Massachusetts, home on Saturday then ‘executed’ two innocent black bystanders in a suspected hate fueled attack, it is claimed.
Nathan Allen, 28, is believed to have deliberately murdered victims David Green, 58, and Ramona Cooper, 60, because of the color of their skin. 

Early in the investigation, police found ‘troubling’ white supremacy rhetoric and statements Allen wrote, which included the superiority of the white race, about whites being ‘apex predators’ and drawings of swastikas, Suffolk County District Attorney Rachael Rollins said.   
Before Saturday’s fatal encounter, Allen wasn’t on her office’s radar. The shooter was married, employed, had a PhD, and no criminal history, and before his rampage on Saturday was not on the radar of law enforcement, Rollins said.
‘To all external sources he likely appeared unassuming,’ she said.
‘And then, yesterday afternoon he stole a box truck, crashed it into another vehicle and a property, walked away from the wreckage interacting with multiple individuals and choosing only to shoot and kill the two black people he encountered.’
Green, was retired Massachusetts state trooper with 36 years on the job, and Cooper was retired Air Force staff sergeant. It’s unclear if the two victims knew each other. 

The incident unfolded Saturday afternoon in the city of Winthrop, about six miles outside of Boston, when Allen crashed the stolen box truck into the building. 
Winthrop police said in a statement that around 2:45 p.m., officers responded to a report of a large truck crashing into a building near the intersection of Shirley and Cross Street. State Police later discovered that the suspect stole a truck “owned by a plumbing and drain company” and then crashed into a house on Veterans Road in Winthrop. The stolen truck belonged to Rapid Flow Inc.
The driver of the stolen vehicle and exited the truck and walked away from the crash before going on to shoot Cooper in the back multiple times and Green in the head, neck and torso, DA Rollins said. 
 “After the truck crashed into the house that is behind us, the driver exited that truck, jumped over a fence and walked down the street. He engaged the first victim and then engaged the second victim, who was further down the street,” Police Chief Terence Delehanty said.
When responding officers got to the scene, a Winthrop police sergeant found Cooper and Green on the ground with gunshot wounds, quickly identified and confronted Allen, and shot him.  

The officer who shot the suspect was taken to a hospital for evaluation, but was not seriously hurt.
Rollins said the police sergeant followed protocol by telling Allen to drop the gun before shooting him and then ‘immediately rendered’ aid.   Allen died shortly afterwards. 
‘This Police Sergeant, like Trooper Green and Staff Sergeant Cooper, is a hero,’ Rollins said on Sunday.
‘The Sergeant stopped a volatile and escalating situation, saving lives, and protecting the community he serves.’
The Winthrop police sergeant who shot the gunman was placed on administrative leave, as part of standard protocol. 
At the news conference, Rollins described the killings of retired trooper David L. Green and Air Force veteran Ramona Cooper as “executions.”
She noted that investigators “found troubling white supremacist rhetoric … in Nathan Allen’s own handwriting,” including “anti-Semitic and racist statements against Black individuals.”
She did not describe the nature of the writings or say where police found them.
Rollins said the case remained under investigation as a hate crime.
She noted that other people in the neighborhood who were not Black had approached Allen out of concern he’d been in an accident. Allen walked by “several other people” who were not of color, she said.
“They are alive,” she said. “Two visible people of color are not. It could have been many, many more.”

District Attorney Rollins did not say where police found the ‘troubling’ racist literature and did not go into any other details about them, but said, ‘There is a growing national, and global, problem with extremism and white supremacy.
‘The FBI believes the most serious domestic violent extremist threat comes from “racially or ethnically motivated violent extremists, specifically those who advocated for the superiority of the white race.”‘ 
Winthrop Police Chief Terence Delehanty told Masslive.com, ‘We have no tolerance for hate in this community.’
Massachusetts state police told Fox News that Green was the ‘quintessential professional’ and are trying to determine if attempted to confront the suspect. 
‘As the investigation continues and resources are extended to the victims’ loved ones and to the Winthrop community, we must say loud and clear that hate has no place in our communities or our nation,’ Rollins tweeted on Sunday. 
The investigation is ongoing.
