One or more shooters could still be on the loose as Ohio officials confirm seven adults and one male juvenile, all members of the same family, were killed at four different Pike County residences Friday.
An initial statement from Ohio Attorney General Mike DeWine said they were "execution-style killings."
"I can say that in this tragedy, 3 children survived," Pike County Sheriff Charles Reader said during a press conference. Reader told press the surviving children were 4-days-old, 6-months-old and 3-years-old.
No one has been taken into custody in the crime that took place near Peebles, about 70 miles (110 km) east of Cincinnati, according to Ohio Attorney General's Ohio Bureau of Criminal Investigation.
The attorney general stated that authorities believe the individual or individuals responsible for the killings are still at large and should be considered armed and extremely dangerous.

"Reports we are receiving from Peebles are tragic beyond comprehension," said Ohio Governor and Republican presidential candidate John Kasich in a tweet.
The Ohio Bureau of Criminal Investigation's crime scene search unit and cyber crimes unit were headed to the scene, the Ohio Attorney General's office said.
The Chillicothe Gazette newspaper showed a picture of three ambulances lined up along a wooded and rural road. It said there were multiple crime scenes, citing deputies on the scene.
