Residents of the rural southern Ohio community of Piketon are rattled by a rare major crime that took the lives of eight members of a tight-knit family known as hard workers.

Authorities were still trying Saturday to find out who targeted the seven adults and teenage boy and why. Their bodies were found Friday at four different homes near Piketon, about 60 miles south of Columbus.

Kayla Hay says she's a former co-worker of one of the victims. She says she never heard 37-year-old Dana Rhoden say anything about being frightened or concerned about anything bad happening.

Outdoors shop owner Todd Beekman says at least one customer has come in to stock up on ammunition after hearing about the shootings.

Investigators say they've questioned more than 30 people.
