Coroner: Mother of kidnapped Southern California girl died of head injury

A woman whose body was found near the remains of her 8-year-old son at a family friend's house near San Diego died of head injury.

Christina Anderson was found dead Aug. 4 when firefighters extinguished flames at the home of James Lee DiMaggio. DiMaggio is accused of murdering her and her son and kidnapping her 16-year-old daughter. DiMaggio was killed six days later in an FBI shootout in the Idaho wilderness. Hannah Anderson was rescued and returned to California.

The San Diego County Medical Examiner's Office says 44-year-old Christina Anderson died of blunt force. It does not elaborate in a brief posting on its website.

A search warrant unsealed last week says firefighters found Christina Anderson's body near a crowbar and what appeared to be blood next to her head.
