832 East Third St, South Boston One of the few houses with a yard, Flemmi's old house can be found at the end of East Third near Pleasure Bay. An identical residence sitting opposite it was former state Senate President William Bulger's.

East Third Street is a quiet thoroughfare lined with trees and modest homes, nestled in a close-knit Irish-American neighborhood. And talk about being a small world. One particular house -- 832 East Third -- was where Stephen J. "The Rifleman" Flemmi's late mother Mary lived. Facing the home's front door is the home of Whitey's younger brother, former state Senate President William M. Bulger, whose two daughters still live on the same street.

It was at Flemmi's mother's house that Flemmi's girlfriend, Debra Davis, was allegedly last seen alive in 1981. She was 26. In 2000, authorities unearthed her body from a makeshift grave by the Neponset River in Quincy.

A cache of machine guns and sawed-off shotguns was allegedly stored in a backyard shed. Michael S. Flemmi, 66, a retired Boston police officer, was arrested in 2000 and charged with helping move the arsenal from a shed in the backyard before authorities raided the home on Jan. 13, 2000. Michael Flemmi was sentenced in September 2002 to 10 years in prison for relocating the stash of weapons for his older brother. He is currently doing time in federal prison in Butner, North Carolina and scheduled to be released in 2011, according to the US Department of Justice's Federal Bureau of Prisons.

Stephen Flemmi is currently serving a life sententce in prison for extortion, money laundering and 10 murders.
