BOSTON -- Stephen "The Rifleman" Flemmi, the once-loyal partner of reputed Boston gangster James "Whitey" Bulger, has recounted multiple killings he says Bulger was involved in, either as a triggerman or a driving force.

Flemmi returned to the witness stand Friday after a brief appearance Thursday.

In rapid-fire succession, Flemmi described Bulger's alleged role in a string of killings during the 1970s when both men were leaders of the Winter Hill Gang.

Flemmi said he and Bulger sprayed a phone booth with bullets in 1975, killing Edward Connors, a bar owner, who was targeted because he was "telling people Winter Hill business," including details about a killing committed by the gang.

Flemmi said Bulger emptied the bullets in a double-barreled shotgun and a pistol, while Flemmi fired seven or eight shots at Connors.
