WOBURN, Mass. – Two men pleaded not guilty at their arraignment Monday to charges they were involved in the shooting death of a veteran police officer who responded to an armed robbery at a department store jewelry counter. One suspect was also killed.

Officer John Maguire was one of several officers who responded to 911 calls about a robbery at Kohl’s just before 9 p.m. Sunday in the midst of a snowstorm.

Maguire was chasing two suspects on foot when the gunfire began. Maguire and 57-year-old Dominic Cinelli, whom police identified as the man who fired the fatal shot, were both struck.

Maguire was taken to Lahey Clinic in Burlington, where he was pronounced dead. Cinelli of Woburn was pronounced dead at the scene.

A visibly shaken Woburn police Chief Philip Mahoney told reporters that Maguire was planning to work one more year before retiring and was moving from the night shift to the day shift in anticipation.

“We do not have shootings in Woburn. It’s not that type of community, and last night Officer Maguire lost his life defending it right in the middle of Washington Street,” he said.

Investigators said the 60-year-old Maguire was shot four times. He is survived by his wife and two children, ages 21 and 22.

Heavily armed police officers and state troopers used dogs to search nearby stores and retail complexes for other suspects, eventually arresting 19-year-old Scott Hanwright and 51-year-old Kevin Dingwell, both of nearby Wakefield.

Hanwright was charged Monday with first-degree murder and ordered held without bail. Dingwell, who police say was the getaway driver, was charged with being an accessory after the fact and ordered held on $1,000 bail.
