Police have issued an arrest warrant a week after eight people were found dead in a mobile-home park in Georgia. Guy Heinze Jr., who called 911 last Saturday and screamed "My whole family's dead!", has been charged with eight counts of first-degree murder. The 22-year-old was also charged with evidence tampering and drug possession just hours after the murders, but police did not say they suspected him of the homicides until Friday. Heinze's father was among the eight dead, which also included four older children and other members of an extended family. A ninth victim, a 3-year-old, remains in the hospital in critical condition.
