At least eight people believed to be members of the same family were found shot to death execution-style in four homes in Pike County, Ohio, and a suspect or suspects may still be at large, officials said on Friday.

The victims included seven adults and one juvenile. All were shot in the head, the Pike County Sheriff and the Ohio attorney general told a news conference. There had been earlier reports that five adults and two juveniles had been found dead.

"We have many horrific crime scenes," Pike County Sheriff Charles Reader said.

An infant less than a week old, a six-month-old and a three-year-old survived the shootings, they said.

Reader said anyone involved in the shootings should be considered armed and extremely dangerous. No arrests have been made. “I am still actively looking for a shooter," he said.

Some of the victims appeared to have been murdered in bed, including the mother of the infant who survived, Attorney General Mike DeWine said. He said that none of the deaths had resulted from suicide. - Reuters
