Police in Alaska have charged a man over the murder of an elderly couple and a brutal sex attack on their two-year-old great-granddaughter.
Jerry Active, 24, was arrested about a street from an Anchorage apartment where 71-year-old Sorn Sreap and his wife Touch Chea, 73, were found beaten to death on Saturday night.
The couple were found by their granddaughter, who had returned from a cinema trip with her husband and four-year-old son. They found their home locked from the inside, broke in through a window and discovered the couple's bodies and a naked man with their daughter in a bedroom.
Sgt Slawomir Markiewicz said the girl's parents tried to detain the man, but he fled wearing just boxer shorts. Police said both Ms Chea and the toddler had been sexually attacked.
Police said Mr Sreap and Ms Chea had suffered significant blunt force object injuries and that Ms Chea had been raped. Police department spokeswoman Anita Shell said investigators were sickened by the brutality and the ages of the victims.
"They said this was the worst thing they had ever seen in their lives, and these are seasoned detectives," Ms Shell said.
The couple were babysitting for their great-granddaughter, who was found with what police said were sexual assault injuries. She was taken to an Anchorage hospital and underwent surgery.
The toddler's parents, along with their children and their own 90-year-old great-grandmother, lived in the same east Anchorage apartment as Mr Sreap and Ms Chea.
Police dispatchers who took the emergency call could hear screaming and a woman said a man had broken into her home and killed her grandmother. The woman described the man as tattooed and fleeing in underwear.
Police detained the suspect about a block from the apartment.
