CARNATION, Wash. – Detectives painstakingly picked their way Thursday through the rural property where six people were killed Christmas Eve, and prosecutors prepared charges against the property owners’ daughter and her boyfriend, authorities said. Hours after the bodies of the victims – three generations of the same family – were discovered, police arrested Michele Anderson, 29, and Joseph McEnroe, 29, according to a law enforcement official who spoke on condition of anonymity because he was not authorized to release the names. King County Sheriff’s Department Sgt. John Urquhart said the suspects went to the crime scene after investigators had arrived, were questioned and arrested Wednesday. Investigators had not found a weapon, and the only hint of a motive they have disclosed is a long-standing dispute between Michele Anderson and her parents. Urquhart declined to elaborate on the nature of the dispute. A law enforcement official identified the victims as Wayne Anderson, 60, and Judy Anderson, 61, who owned the property where the killings occurred; their son, Scott; his wife, Erica; and their two children, Olivia and Nathan. The official spoke on condition of anonymity. The sheriff’s office would only say the victims were the homeowners, ages 60 and 61, their daughter and son-in-law, both 32, and the younger couple’s 6-year-old daughter and 3-year-old son.
