(Portland, OR)  --  An investigation is ongoing into the discovery of a missing Salem woman's body in the Santiam State Forest.  Police found the body of 35-year-old Amber Jayne Eldridge yesterday in steep terrain about 700 feet from her vehicle.  Deputies had found Eldridge's one-year-old granddaughter safe inside that vehicle on Saturday morning.  Investigators say Eldridge messaged a loved one Friday night saying she had driven to an area off Sawtell Road to get away for a bit and that her granddaughter was with her.  Police say they don't suspect foul play in the death.
