PIKETON, Ohio (AP) — Authorities were tight-lipped Wednesday about their investigation into the slayings of eight family members in a rural part of the state, and the attorney general said they wanted to avoid informing the killer or killers about what they know. Authorities say they've interviewed more than 50 people but haven't made arrests or confirmed a motive for the slayings. Seven members of the Rhoden family were shot multiple times, and one had nine gunshot wounds, a coroner said. Authorities said it was unclear what, if any, role the marijuana discovery would play in the investigation. [...] while DeWine said he understands that people care about the victims and want to help, he warned of a scam in which someone was claiming to be from the sheriff's office and was asking for donations.
