Three young children survived the series shooting that took lives of eight people, all from the same family, police in Pike County, Ohio said. A 16-year-old male is among the dead. The suspect is still at large and considered dangerous.

The surviving children are 4 days old, 6 months old, and 3 years old, Pike County Sheriff Charles Reader said during a Friday afternoon press conference. They are all members of the Rhoden family.

Reader said he knew the family because Pike County is a small community, but refused to say anymore about them because they are grieving and he wanted to respect that.

“We are doing everything in our power to reach out to the [surviving] Rhodens,” he added.

The first 911 calls were received around 7:53 a.m. local time, notifying police of two males covered in blood at a home, Reader said. While they were responding to the first location, sheriff’s deputies were flagged down and given two additional addresses. There they found additional victims who had been shot and killed.

“Each one of the victims appears to have been executed. Each one of the victims appears to have been shot in the head,” Ohio Attorney General Mike DeWine said, noting that none of the individuals appeared to have committed suicide, leading law enforcement to suspect that at least one shooter remains at large.
