SAN DIEGO -- Search warrants say a family friend tortured and killed a mother and her 8-year old son before setting his San Diego-area home on fire and fleeing with the woman's 16-year-old daughter.
The warrants unsealed Wednesday say James Lee DiMaggio and Hannah Anderson exchanged about 13 calls before Hannah was picked up from cheerleading practice on Aug. 4.
Both phones were turned off, and the home burned several hours later.
The warrants do not describe the torture but say the body of 44-year-old Christina Anderson was found in the garage near a crowbar and what appeared to be blood next to her head. The body of Ethan Anderson was found as investigators sifted through rubble.
Hannah Anderson was later rescued when the FBI killed DiMaggio in the Idaho wilderness.
