Is it possible that the Black Dahlia killer was also the Zodiac Killer?

I mean both were never caught and in California. Black Dahlia was around 1945 and Zodiac 1969 (possibly 1966) - 1974 but if the BD killer was 20 in 1945 he would be in his 40's during the Zodiac crimes which almost every suspect is. And if you haven't already seen, Dennis Kaufman has VERY unclear but identifiable (as a person) pictures of a girl strapped down on a table or something which a missing jaw which he has given to the FBI for resting I guess he also thinks his step-father Jack Tarrance is the Zodiac and had a while website placing him at the zodiac crime scenes with actual doentation such as court orders and other things
