BOSTON — At the height of his criminal empire in South Boston in the early 1980s, ruthless gangster James "Whitey" Bulger had three victims buried in the dirt-floor basement of the same house where he had just killed them.

More than three decades later, the house that Bulger called "The Haunty" is on the market, and the asking price is hefty: $3.5 million.

The Boston Globe first reported that the house at 799 East Third Street in trendy South Boston is for sale. An online listing bills the Cape-style home, which consists of two attached houses, as a "development opportunity." The house is in the City Point area of the South Boston neighborhood, a couple of blocks from the waterfront and a park.

The property during the time of the murders belonged to the brother of Pat Nee, a Bulger associate, the Globe reported. The bodies were relocated to a location in the Dorchester neighborhood in 1985 before the house was sold, according to the newspaper.

The interior of the house, built in 1885, is now stylish and modern with shiny hardwood floors and colorful walls. The high price tag reflects the red-hot housing scene in South Boston, historically an Irish-American working class neighborhood that is now a hotbed for young professionals, house-flipping projects and new condos.

The real estate listing makes no mention of the home's dark history.

Bulger, onetime leader of the Winter Hill gang, was bludgeoned to death at the age of 89 in prison in October as he was serving two life terms for the killing of 11 people in addition to numerous counts of extortion, money laundering, drug dealing, and firearms possession. He faced charges related to 19 murders.

Testimony during Bulger's 2013 trial in Boston federal court, according to the Globe, revealed three people were killed and buried in the South Boston house: Deborah Hussey, the 26-year-old daughter of the girlfriend of Bulger's partner Stephen “The Rifleman” Flemmi, in 1985; Arthur “Bucky” Barrett in 1983; and John McIntyre in 1984.

The house is currently owned by Russell and Mary Radcliffe, according to the Boston City Assessing Department. It was sold by Michael and Kathleen Nee to the Radcliffes in 1985 for $120,000, according to records from the Suffolk County Register of Deeds.

The Globe quoted the listing broker, Sara Walker, describing the current owners as a a “wholesome, hard-working” couple who raised their family in the house. Walker told the newspaper the new development is "a wonderful opportunity for the neighborhood to heal."

During the Bulger trial, Flemmi testified that Bulger strangled Hussey, 26, because she was using drugs and dropping their names when she got in trouble.

“It didn’t take long,” Flemmi told the court, according to Reuters. “She was a very fragile woman.”

Bulger then went upstairs to take a nap, Reuters reported, while Flemmi and others dug her grave in the basement.

Bulger had Barrett, an alleged jewel thief and bank robber, chained to a chair and he shot him in the head after he told Bulger where he had cash hidden. McIntyre was also shot in the head after Bulger interrogated him about talking to authorities. The two men were buried in the basement with their teeth removed to help hide their identity.
