An unhinged man crashed a stolen box truck into a house, then got out of the vehicle and shot two people dead — before he was killed by police outside of Boston, Massachusetts on Saturday.

The mayhem unfolded at around 2:40 p.m. in a residential area of Winthrop, after the gunman flattened a home with a truck he’d swiped from a plumbing and drain company, according to NBC 10 Boston.

He then got out of the truck and gunned down a woman and a man, the station said.

Officers responding to the chaotic scene fatally shot the shoeless suspect, according to the local outlet.

Massachusetts State Police were investigating whether the two victims had been trying to stop the shooter when he killed them.

Two people in another vehicle were injured in the crash, and were being treated at the hospital, the report said.

It’s unclear if the suspect was connected to the plumbing and drain cleaning company that owned the truck, or if he was targeting the victims, according to the report.

Emely Norena was in bed when she heard a big crash. She reportedly heard another crash after she ran outside to help the people in the car.

“Then all of a sudden, I hear a set of gun shots. Then I ran back inside my house,” Norena told the station.

“I feel like my mind went blank. All I was trying to do was get my mom to safety because the gunshots really scared me. Winthrop is known to be a very safe town. Not many things like this happens around here, so it scared me a bit.”

Witness Robert Harrington gave a detailed statement to the station about the incident.

“He climbed out of the truck, climbed over the fence. He had no shoes on, he looked like he was out of it. I don’t know if he was disoriented or whatever. And then he just started casually walking down the street. I was going to say something, but what am I going to do, you know what I mean?,” Harrington reportedly said.

“Then, he started jogging. Then, I heard the ‘boom, boom, boom, boom.’ Then, I ran down, I looked down and the next thing I saw is the body in the middle of the street. So, I ran down, got behind the car, ’cause the shots were still going. You could see the smoke from the gun.”

“To tell you the truth, the girl, it makes me very sad. I just thought I’d block it out and try to go on with my life, but it’s definitely going to stay with me.”

The plumbing company, Rapid Flow, Inc., acknowledged the incident in a Facebook post.

“This afternoon one of our trucks was stolen, and unfortunately was just used moments ago to drive through a Winthrop residence. We will keep you updated as more information becomes available,” the post read.

The house that was flattened by the box truck was unoccupied, according to the article.
