(Grants Pass, OR) -- A man accused of kidnapping, confining and torturing a woman nearly to death in southern Oregon last week is now also believed to be responsible for two murders. Josephine County Sheriff's deputies say they saw signs of a crime in a home while canvassing Sunny Valley during their search for 36-year-old Benjamin Obadiah Foster earlier this week and found two people dead. Investigators believe Foster killed them and then took a cab to the home in Grants Pass where he ultimately shot and killed himself following an hours-long police standoff Tuesday night. Foster was accused of kidnapping a woman, torturing her and trying to kill her, less than two years after being convicted of doing the same thing in Nevada. Police found the victim unconscious, bound and near death in Grants Pass last week Tuesday. She remains hospitalized in critical condition.
