A woman pleaded guilty to helping plan the killings of eight members of a family, becoming the second member of her own family to admit to a role in a shocking crime prosecutors in the US state of Ohio say stemmed from a dispute over custody of her granddaughter.

Angela Wagner, 50, pleaded guilty in southern Ohio’s Pike County to conspiracy to commit aggravated murder, along with burglary, evidence tampering and other charges.
