Selectmen have conditionally appointed two police officers to fill vacancies on the force, according to Town Administrator Michael McCue. Both men — Brian T. Timulty of Braintree and Manuel J. Valenzuela of New Bedford — are veterans, McCue said. Timulty served in the Army and Valenzuela was in the National Guard. After medical screenings, the two will attend the next Police Academy in Plymouth and then be sworn in as full-time officers. “We welcome these two men to our department and hope they have a long successful career here,” Selectman Chairman Frank Hegarty said in a press release.
