Volpe to transfer control of the department from the Governor of Massachusetts to the Mayor of Boston On April 5, 1962, Volpe officially ceded control and Mayor John F. Collins sent a cable from Italy, where he was vacationing, to confirm McNamara's appointment as commissioner.

McNamara submitted his resignation to Boston's special agent in charge Leo L. Laughlin that day and assumed control of the department on a temporary basis.

McNamara was the first career law enforcement officer to serve as Boston police commissioner in the twentieth century.
