I did a search and could not find anything on this person - http://www.crimelibrary.com/photogallery/serial-killers-killed-in-prison.html?curPhoto=5 Known Victims: Murdered - Jacqueline Anne Rook, Nov. 20, 1976, aged 21 - Isla Vista Murdered - Mary Ann Sarris, Dec. 6, 1976, aged 19 - Isla Vista Murdered - Patricia Marie Laney, Jan. 18, 1977, aged 21 - Isla Vista Murdered - Laura Sue Benjamin, May 26, 1979, aged 22 (body found, Los Angeles) Attempted Murder/Survived - Prostitute picked up from Los Angeles who he shot in Hollywood Hills In the youtube video below: Serial Killer - Thor Christiansen: The Hitchiker Slayer, it was asked if Christiansen could have killed more victims - (39:00 mark) - the answer from the LE being interviewed said 'YES' - Christiansen moved to Oregon and there had been murder cases there which fitted his timeline and the way he killed. Police could never get out of him where in Oregon he was during those 22 months. Christiansen also mentioned to a friend he went/wanted to be a long haul truck driver - which he may have done when he moved to Oregon. [ame="http://www.youtube.com/watch?v=s2L9mGAIbJw"]Serial Killer - Thor Christiansen : The Hitchiker Slayer - Documentary - YouTube[/ame] I was wondering if you know of any Cold Cases which would fit Christiansen's timeline: between 18th January 1977 - 7th July 1979 (arrest date). I also wonder about victims that may not have been found, or were found after this date and were UID's in California or Oregon. Known: He picked up Hitch Hikers and had been frequenting known street sex work area looking for girls. He shot girls in the head He sexually assaulted them after their death He would dump them from the car along the roiadside - later dumping his last victim in a dam in a secluded area. He used a .22 caliber pistol he had stolen for 3 of the murders.
