WHO would KILL a vacuum salesman?

John Parker Jr. was shot twice in the back of the head in his office parking lot. His wallet was stolen, leading Detective Toth to initially suspect a robbery. However, the lack of defensive wounds and the precise shot suggested a planned execution rather than a chaotic mugging. Witnesses included John's wife, Judy, and his office manager, Barry Jones.

John's body found with expensive jewelry untouched, a shot behind the ear, and the secluded location of the office park. Judy's shifting demeanor during interrogation and her affair with Barry, combined with John's recent firing of employee Derek Hall, created multiple early suspects.

Despite multiple suspects and leads, including John's wife Judy (due to an affair with Barry and a large life insurance policy), Barry Jones, and disgruntled ex-employee Derek Hall, the case went cold for four years. No forensic evidence linked anyone directly to the crime. The breakthrough came in 2007 when a man arrested on drug charges offered information, claiming his housemate was involved in John Parker's death.

Detective Toth's inability to find concrete evidence to link Judy or Barry to the murder, or to confirm Derek's involvement. The tip from a narcotics arrestee provided the crucial new lead, revealing a far more twisted plot.

The investigation revealed that John's wife, Judy, orchestrated his murder. She convinced her 15-year-old son, Daniel, to shoot John, with her daughter Christina assisting by finding the gun. Judy's motive was financial: she wanted to collect John's $1 million life insurance policy and his $2 million estate, which she would only get half of in a divorce. She had previously attempted to kill John through poisoning and hiring a hitman, both unsuccessfully.

The confession from Christina's husband, followed by confessions from Christina and Daniel. Daniel's initial attempt to hire other kids for the job, and his use of his younger siblings as an alibi, confirmed the premeditated nature of the crime.
