Despite a neighbor’s rescue efforts, a man in his 30s was killed in a two-alarm fire that engulfed the kitchen of his ­Attleboro home early Monday, fire officials said.

The fire broke out in the home on Woodstock Road around 12:45 a.m., said Deputy Fire Chief Erik Guillette.

Officials from the state fire marshal’s office are investigating the cause of the blaze, he said. Guillette was unsure whether the house had working smoke detectors. The name of the victim was not released by officials.

Two dogs were in the house when the fire broke out, Guillette said.

“One of the dogs ran out the front door,” and the other was rescued from a crate in the basement, he said.

Sandra Robinson, 64, lives next door to the home and was asleep when the fire broke out.

“The flames were about 200 feet from our home and when I heard some noises, I looked out and I could see flames shooting off the deck,” she said. “I woke my husband and we fled right away.”

Guillette said firefighters found the victim, who was home alone, near a sliding glass door leading to a back deck.

Another neighbor tried to save the man’s life.

Robinson got to the scene moments after the other neighbor used a ladder to climb onto the back deck, which was about 10 feet off the ground.

“They ran their ladder across the street and climbed up over the railing for the deck and tried to see if they could get in,” Robinson said. “There were some popping noises and they were unable to get [the man] out.”

Robinson, who has lived on the street for 11 years, said the victim lived with his mother and that his father had died two years ago.

“Since then he has been with his mother, who is not well,” she said. “He spent a lot of time taking care of her. The two things that were consistent with [him] were his dogs and his mother.

“One dog escaped relatively early,” Robinson said. “We thought the Chesapeake Bay retriever puppy had been lost in the fire, but 30 minutes later we were able to get him.”

Stephen Ebert, 46, lives across the street from the house and said “the whole west side of the house was engulfed.”

Ebert said he had seen the man walking the two dogs less than an hour before the fire broke out.

He “just adored” the dogs, Ebert said.
