The Murders Before the Marathon

A triple homicide in Waltham sparks journalist Susan Zalkind to investigate the murder that took her friend's life, the national tragedy that shook her city, and the possible haunting connection between the two events.

Susan chases down leads and examines the motives of the possible killers; a murder at the hands of the FBI raises more questions than answers.

The Supreme Court provides new evidence pointing toward fatal flaws in the investigation, where the Boston Marathon bombing maybe could have been prevented.
