On New Year’s Eve 1980, a Phoenix family is getting ready to host their holiday party, when three strangers show up at their door, and one of them dressed as a police officer. Everything takes a turn when the three men tie up the family members and shoot them execution style. However, one of the three survived. It turned out that the murders weren't random at all, but a deliberate plan orchestrated by the Mafia, and the corrupt ties spun a complicated web between Phoenix, Las Vegas, and Chicago. Three men were sent to death row for the killings, but only one is still alive today: Murray Hooper. Now, a court decides if "The Last Hitman" will finally be put to death in Arizona 40 years later.

The new limited series of True Crime Arizona premieres January 30.
