Corey King (pictured), 18, of Altadena, who was arrested in the killing of a mother and three children in Lancaster, turns out to have ties to the Mosely family. The bloodied body of Evelyn Mosely, 90, was discovered by firefighters May 8 after a fire had been set in her home. In the Lancaster case, Sonya Durfield, 42, and her three daughters, ages 14, 12, and 8, were likewise found murdered in Durfield's home in Lancaster as the house burned. King -- who it turns out knew the Mosely family -- will be arraigned this morning in the Durfield case and is being questioned in the Mosely case. KNBC is first out of the blocks with this story.
The ever-puzzling Contra Costa TImes also has a take on it.
10:30 PM Update: SFGate (the San Francisco Chronicle's website) says that King, who pled guilty to petty theft in August, was working as a trusty at the Altadena sheriff's station, doing menial work such as emptying trash cans and washing patrol cars.
