Justice for Sean Ellis

Sean K. Ellis was convicted in 1995 (after two mistrials) for the 1993 murder of Boston Det. John Mulligan. He was incarcerated for nearly 22 years, but his conviction was overturned in 2015 by a Suffolk Superior Court judge who ruled "justice was not done." This website tells his story.
