Police in Guyana are looking for a man they say raped a 13-year-old girl and killed her mother and brother in an attack near a rural mining town in the South American country.

Police spokesman Ivelaw Whittaker said Saturday that 33-year-old Molly James and her 15-year-old son, Aaron, were stabbed to death on their farm near Linden. He said the man had run away after raping the girl but later returned to kill her family after learning police were looking for him.

Whittaker said the girl escaped the attacker after being sexually assaulted.
