Five Four Two and the Blue episode - 13 – 1901  murder of a sleeping family.  

On the night of September 21st, 1909, a knock on a cabin door and a neighborly welcome turned to murder.  The family knew the visitor and quite naturally opened their home to him. By nine o’clock, all six family members were asleep. Using a pistol, a knife, and a hatchet the visitor is said to have slain the entire family, then set the cabin on fire and left.

Bungled petty theft and non-premeditated murder. Or a planed ruthless killing of an entire family over money.
