That same November night a Dedham police officer, Warren Totty, standing under the arc light in the granite shadow of Memorial Hall, had seen the car speeding across Dedham Square. He had stepped out with his hand raised, but the car swung past him down the hill and under the railroad bridge toward Hyde Park. The license number that Totty managed to copy down turned out to be Murphy’s. “It is thought,” Hellyer reported, “that this car may have been used by the men last Wednesday.” The connection between the Murphy Buick and the Needham license plates appealed to Stewart, even though both Graves and Harding had said that the car was a Hudson. Hellyer now interviewed Richard Casey, a student at Rhode Island State College, who had seen the car on Main Street before the shooting, and John King, who noticed it afterward near the normal school. Whether or not Chief Stewart had prompted them, both said it was a Buick. Stewart and Brouillard had managed to trace the car as far as Stoughton. Beyond that point, although they called at all the garages in the vicinity, their leads came to nothing. Chief Shine of Dedham had a notion that an Italian gang in East Dedham might be involved. Stewart visited Dedham, Needham, even some suspects in Newton, and arranged meanwhile for circulars describing the car to be distributed to the local garages and gas stations. He now began to think the car was hidden somewhere between Stoughton and Dedham. Meanwhile the Pinkerton agents had been spreading out through the Italian districts of Quincy and Boston. On December 30 Assistant Superintendent Henry Murray reported: _Today informant telephoned in; later met him at supper and in the course of conversation stated that he had learned that the Italian mentioned yesterday had said that the men who were implicated in the Bridgewater holdup had occupied temporarily a shack in close proximity to Bridgewater and that the car that had been used was left there along with some overalls or disguise of a similar nature, used by one of the men implicated in the holdup; that these men were Italians, had deserted the car, returned to Quincy by trolley; that they are believed to be residing in the vicinity of Fore River Shipyard and are known as Anarchists._
