FILE -The Common Grounds coffee hut is seen on Wednesday, Jan. 23, 2013 in Anchorage, Alaska. The Common Grounds is the location where barista Samantha Koenig was kidnapped by Israel Keyes on  Feb. 1, 2012.   Keyes showed no remorse as he detailed how he'd abducted and killed an 18-year-old woman, then demanded ransom, pretending she was alive. His confession cracked the case, but prosecutors questioning him soon realized there was more, he has killed before.  Before divulging more details, Keyes committed suicide in his cell.
