Young children spared, 8 family members killed in Pike County, Ohio shootings

"It's heartbreaking," Ohio Attorney General Mike DeWine said. "The one mom was killed in her bed with the 4-day-old right there."

In a joint statement, DeWine and Reader said the deaths appeared to be "execution-style killings."

"The investigation will go wherever the facts take us," he said. "Investigations like this can take a while."

"This is a horrible tragedy that has occurred here in Pike County," DeWine said. "We advise Pike County residents not to panic but to be careful."

"Dana loved her family. She worked hard," Fulton said. "What a tragic thing, a tragic thing. … We just have to lift this family, this community and this whole country up in prayer."
