As the investigation into the killings of eight family members in rural Ohio enters its fifth day, more details are being released.

Pike County Prosecutor Rob Junk told The Columbus Dispatch Monday that the marijuana operations discovered at three of the four crime scenes included a grow-house sheltering hundreds of plants.

Ohio Attorney General Mike DeWine also says there's possible evidence of cockfighting at one of the properties, but he says he doesn't know what's relevant to the investigation.

No arrests have been made, and officials have not said if they have any suspects in mind. They have not released any details about a motive.

All eight victims were fatally shot in the head on Friday in Piketon. They're being remembered as loyal and caring people.
