In the dictionary next to the definition of “dogged reporter” there’s a picture of Maureen Boyle. Or there ought to be. She covered the worst serial killing case in Massachusetts since the Boston strangler and, when no indictments were handed down, kept at it, interviewing cops, DA’s, witnesses, victim’s family members for over 25 years. This is a painstakingly granular, step by step chronicle of a horrific series of murders of eleven young women that has still never been solved.
