A two year old boy is in state custody after being found home along with his deceased mother.  The woman suffered from medical issues, and a friend found her dead in her southeast Portland home.  Sergeant Pete Simpson says the boy was hungry and thirsty, but otherwise ok.  He was taken to a hospital as a precaution.  The state is working to locate relatives and determine custody.  It appears the woman died of natural causes.  The medical examiner will determine the official cause of death.
