I think the glory days of the white serial killer preying on coeds is largely a thing of the past, a relic of the 70s-80s.
Serial killers now have been majority black for quite a while, and usually murder street people or other high-risk individuals who are not quickly missed.
Yeah, the "free love" period attracted a lot of nasty guys, no surprise there.
Apparently so, as I have been schooled on this thread.
