Trumbull County Asst. Prosecutor Chris Becker says Donna and Nate Jackson put so much planning into the murder, but acted stupidly with their letter-writing and phone calls in the jail.

Sheriff Paul Monroe says the murder scene didn't look like a typical burglary, and that from the start, officers knew something wasn't right with Donna Roberts. Proving her involvement in the murder would be a process, though.

Donna Roberts was in a car wreck about a year and a half before Fingerhut's murder. Her son says that after the accident, she was never the same.Her voice even sounded "semi-different" on the phone, he says.

Acquaintances of Donna Roberts recall her "flirtatious" and "bubbly" personality, which she brought with her to Miami, with her first husband, William Raymond.

The marriage between Donna Roberts and Robert Fingerhut seemed happy, but secrets bubbled beneath the surface, eventually erupting in a shocking murder.
