MURDERED: Adriane Insogna and Leslie Mazzara (Season 3 Ep. 16)

On Halloween Night in 2004, three roommates were handing out candy to trick or treaters before going to bed.  What had been a peaceful night quickly turned into terror when somebody broke into their home and killed both Adriane and Leslie.  For over a year, the murders remained unsolved, until new evidence came to light and the pieces started coming together.
