charged with killing her. people thought, debra s psycho ex-husband has murdered melissa. you know, i was just overwhelmed with guilt and shame. reporter: melissa s murder weighed heavily on debra s mind, as well as the mind of her boss scott rothstein. but scott seemed to be rattled by something more than just melissa s murder. for some reason after tony s arrest, rothstein beefed up his own security. who was he afraid of? obviously that he was next. reporter: but if melissa s murder had been solved, why was scott still worried? debra knew because she was privy to a secret that threatened to send even more people to prison, and to destroy scott rothstein s reputation as a high-profile mover and shaker. he could pick up the phone and call and make things happen. reporter: a walk through his office left no doubt. his hero wall was plastered with pictures of him with politicians, business moguls, and movie stars. the governor was on speed dial.
