While driving through Grasshopper Junction, which is 30 miles north of Kingman on the way to Las Vegas, they stopped at the home of Dean Morrison and Jackie Appelhans.
The Murrays entered the home while armed, and had the two victims lie down on the floor side-by-side. They shot each of them at least twice with a .38 revolver, and shot Jackie twice more with a .22 rifle. They then shot each of them once in the head with a shotgun. They then ransacked the house and fled.
