A shooter is on the loose after at least seven people, some of them children, were killed at three different crime scenes in southern Ohio Friday, local news agencies report. One of the scenes is a home east of Peebles in Pike County. Ohio’s Bureau of Criminal Investigation sent more than a dozen agents to investigate.

Sources tell the news station investigators don’t believe the attacks were random. All seven people who died were family members

Peebles High School and all Adams County Ohio Valley Schools went on lockdown,

A spokeswoman for Ohio’s attorney general Mike DeWine told the Chillicothe Gazette nobody had been arrested as of Friday morning.

The bureau sent crime scene investigators, special investigators, criminal intelligence agents and cyber crime investigators, Fox 19 adds. they sent so many agents because they’re not sure exactly what unfolded at the home.

Police closed off roads around the home. Pike County is roughly 80 miles east of Cincinnati and 70 miles south of Columbus.
