Authorities say they found marijuana-growing operations at three of the four locations where eight family members in rural southern Ohio were found fatally shot.

They said at a news conference Sunday that it's unclear what, if any, role the growing operations had in Friday's killings. Seven adults and a teenage boy, all Rhoden family members, were found shot in the head at homes near Piketon, about 60 miles south of Columbus.

Attorney General Mike DeWine called the slayings a "pre-planned execution."

DeWine and Pike County Sheriff Charles Reader would not comment on a possible motive, but said the investigation will be lengthy. More than 100 personnel are assisting in the investigation.

Autopsies on the bodies are expected to be completed Monday.
