19 - 25: The Puppet Master

Newlyweds Heather and John Grossman were driving to lunch 10 years ago on a sunny Florida day when bullets suddenly pierced their vehicle. John survived the shooting but a bullet ripped a fist-sized hole in Heather's neck, severing her spinal cord leaving her a quadriplegic. Investigators found the shooter, Roger Runyon, who detailed how he used a long rifle to fire at the Grossmans. But investigators also uncovered three other men who allegedly conspired with Runyon. Yet investigators soon realized that the case against the group was missing one big piece -- the puppet master -- the person investigators believed to be responsible for planning the crime.
