Ohio's attorney general says authorities have no new information to indicate whether there's an ongoing threat to relatives of eight family members slain in southern Ohio.

The eight people were found shot in the head at four homes near Piketon on April 22. Authorities say the deaths were a sophisticated operation, but they haven't released any specifics on suspects or a motive.

A sheriff had said other members of the Rhoden family should arm themselves.

Attorney General Mike DeWine told The Associated Press on Monday that authorities didn't know whether there was a threat to the family and he wouldn't speculate about whether a threat remains.

Services have been held for two victims. Funerals for the other six are Tuesday. DeWine says there will be "ample security" at those services.
