San Diego County sheriff's officials say the bodies of a woman and child have been found inside a burned house, and a man is suspected of killing the woman and abducting one or both of her children.

Sheriff's investigators said in a statement Monday night that the body of 44-year-old Christina Anderson was found Sunday night in the unincorporated community of Lakeside. In the burned garage was the body of a child whose identity and manner of death remain undetermined.

The suspect is the house's owner, 40-year-old James DiMaggio. Authorities say he was in a close platonic relationship with Anderson.

Officials say Anderson's 16-year-old daughter Hannah and 8-year-old son Ethan are missing, and it is believed Anderson may have abducted them.

An Amber Alert has been issued for DiMaggio's blue Nissan Versa.
