For notoriety I would add the Boston strangler to the list. Very big in the 60's.

And one of the most overlooked serial killers ever is David Carpenter, aka "The trailside killer", from the San Francisco area in the late 70's and early 80's.

Get the book "The Sleeping Lady" for the full story on this guy, it's quite an interesting read.
