UPDATE | At least 8 dead at 4 locations in Ohio; no arrests made

PIKETON, Ohio (AP) — Eight people were found dead today at four crime scenes in rural Ohio, and at least most of them were shot to death, authorities said. No arrests had been announced, and it's unclear if the killer or killers are among the dead.

Seven of the victims, including two children, were slain in "execution-style killings" at three homes along a rural road, authorities said.

Details on the death of the eighth person weren't immediately available, but the body was found in a fourth location, said Jill Del Greco, spokeswoman with the Bureau of Criminal Investigation. Attorney General Mike DeWine planned to provide an update in Pike County later Friday afternoon, she said.

DeWine and Pike County Sheriff Charles Reader had said earlier that seven victims were believed to be members of the same family. All were shot to death, they said.

There is not an active shooter and no arrests have been made, DeWine and Reader said. Authorities are trying to determine a motive, identify the deceased and determine if the killer or killers are among the deceased individuals or on the loose.

A dozen BCI agents were called this morning to Pike County, an economically struggling area in the Appalachian region some 80 miles east of Cincinnati.
