Three people were shot to death at an Idaho pit-bull business that doubled as an indoor pot farm, cops said.

Brent Christensen, 61, his son, Trent, 32, and Yavette Carter, 27, were found dead by a customer who was there to buy a dog.

Authorities also found two young children on the property, who were unharmed.

Police believe the animals were bred for illegal dogfighting.
