A heated dispute between neighbors led to the fatal stabbing of a man in Dorchester yesterday, police said, as a neighbor suggested the fight may have been sparked by a disagreement over discarded beer bottles.

Hub cops responding to a reported double stabbing on Bradshaw Street at about 8 a.m. found a man in his 40s who had been stabbed multiple times, police said. The man, whose name was not released last night, was rushed by ambulance to Tufts Medical Center, where police say he was pronounced dead.

The other man involved in the violent confrontation, who police also described as a man in his 40s, transported himself to Boston Medical Center with apparent stab wounds, officials said.

Department spokeswoman officer Rachel McGuire said the two men were neighbors who knew each other.

As officers scoured a multifamily home on Bradshaw Street for evidence yesterday, blood stains could be seen on an interior wall and along the floor of a hallway leading to a set of stairs. A neighbor who asked not to be named said she overheard the victim’s girlfriend arguing with a neighbor Wednesday over discarded beer bottles that had been left on a front lawn. The neighbors, she said, have a contentious relationship.

“They were arguing about trash,” she said. “Beer bottles left on the yard.”

The woman said the sound of screaming yesterday morning drew her out of her apartment, and as she searched for the source of the commotion she found a blood-soaked man moaning in pain with towels wrapped around his torso.

A man and woman who appeared to know the victim declined to comment. One woman could be seen weeping on the building’s front porch.

Ansy Chevalier, who described himself as a friend of the man who was killed, said the possibility that his pal died in a fight over trash was shocking.

“That’s not worth dying for,” he said, adding that his friend was a doting father to more than one child and was an all-around great person.

“He was a good man. He was a loving father,” Chevalier said. “It’s a sad day. It’s overwhelming. I really can’t believe it.”
