As the rural Appalachian community of Peebles, Ohio, reels from the execution-style killings of eight local family members, authorities are scrambling to solve the mystery of who could have committed such a brazen, ghastly act at four homes only miles apart.

The carnage revealed itself slowly as sheriff’s deputies moved from home to home, drawn first by a 911 call and then by the horrifying realization that the victims were killed at four locations in this otherwise serene farmland area 70 miles east of Cincinnati.

Some might have been sleeping when the killer came for them before dawn Friday. Men and women. A teenager. A young mother in bed with her 4-day-old baby.

All members of the same family, all shot at least once in the head.

Police detained a “person of interest” in Chillicothe late Friday for questioning, but Ohio Attorney General DeWine said the person was one of 30 people interviewed in connection with the case, some of whom were from Chillicothe, located about 40 miles northeast of the crime scenes.
