WOBURN (CBS) — Dozens gathered for a moment of silence for Officer Jack Maguire at the sight where the Woburn police officer was shot exactly one year ago. His widow Desiree was surrounded by family, friends and fellow officers, who came to show support.

“Jack went out a hero, and we’re here for the family,” said Tim Donovan, a Woburn detective. “The one thing it’s done for us it’s brought our department tighter together.”

The tragedy sparked outrage. Cinelli was out on parole after serving part of his life sentence. Chuck Maguire said, “I was just shocked by how they let this guy get out.”

After Maguire’s death, all five Parole Board members who released Cinelli resigned. Governor Patrick replaced the Parole Board members with people with a wider range of experience, including former prosecutor Josh Wall as Chairman, as well as a forensic psychologist and a corrections professional.

They have overhauled the system, to give board members more information and require more extensive hearings for people like Cinelli, who have life sentences with the possibility of parole.

Maguire’s family likes those changes, but says the state needs more parole reform. A bill is now in a conference committee. Chuck Maguire says he supports the current Senate bill. Prosecutors have written letters stating that the House bill wasn’t tough enough.
