S4 E106 | The Last Supper

An Arizona couple can't agree on how to spend their retirement savings, and neither one will budge without getting what they want. But the bickering ends tragically when a hitman shoots the couple's pickup truck right in broad daylight outside a restaurant, killing one of them. The survivor is too distraught to remember many details about the attack, and years go by until police plant a fake story to try to catch the killer.
