A man allegedly threatened and attacked an Asian family outside of the post office near 40 Washington St. in Quincy, MA shortly after 10:55 a.m. on Friday, December 2. Authorities say 77-year-old John Sullivan is facing two counts of assault and battery with a dangerous weapon, reckless operation of a motor vehicle, leaving the scene of a crash with personal injury, and a civil rights violation.

According to Desiree Thien, she and her three children and her adult brother were on Washington Street when they witnessed Sullivan speeding in his car. Thien’s brother confronted Sullivan about the speeding before Sullivan allegedly went on a racist rant. Thien spoke to WCVB5 and said Sullivan yelled, “Go back to China. I'm going to go into the post office and come back out in five minutes. If you're still here, I'm going to kill all of you!”

Thien said she and her brother were standing in front of Sullivan’s car, collecting his information before Sullivan got back into his car and hit her brother. "My brother pushed me aside and then the car hit him. He went rolling onto the hood. Sullivan abruptly stopped on the break. He fell down and was trying to balance when Sullivan threw racial slurs at him again and he said ‘I am going to kill you’ and he rammed into my brother again which sent him flying into the construction ditch,” Thien said to Boston 25 News.

The construction ditch Thien’s brother was knocked into was an estimated 10-15 feet deep, according to authorities. The victim is recovering from multiple injuries including concussions, fractures, and torn ligaments.

According to Quincy police, there was a witness who followed Sullivan and provided locations to dispatchers who then relayed that information to Braintree police. Braintree police officers were able to locate Sullivan on Quincy Avenue and arrest him.

“Being hateful and racist is one thing, but you drop down to pure evil when you target children. For my kids, they do not deserve to be witnessing or even be a part of this discrimination toward them,” said Thien. “I want him for the rest of his life to stay in prison where he belongs because he is a danger to society. He is 77 so Satan is waiting for him with open arms.”

Sullivan pleaded not guilty to the charges brought against him when he was arraigned Friday in Quincy District Court.

Sullivan is being held without bail until his hearing which is scheduled for Wednesday of this week.
