Serial killers

Frank, I’ve been doing in depth research on serial killers and their behavior ect. I am wondering what serial killers are still alive and who to most recent serial killers are.
Thank you,
Elisabeth, Long Beach, California.

Dear Beth, Love Long Beach I lived there for 10 years, good question and interesting subject.
You can goggle these for your history but here are some names of the sickos:

Gary Ridgway 
David Berkowitz 
Dennis Rader 
Karla Homolka 
Paul Bernardo 
Clifford Olson 
David Russell Williams 
Robert Pickton 
Rose West (serial pedophile. serial child and woman killer.)
Charles Manson (some don't consider him a serial killer) 
Scott Lee Kimball 
The Yorkshire Ripper - Peter Sutcliffe (prostitute killer)
Ian Brady (serial child killer)
Steve Wright (prostitute killer) - (Ipswich strangler)
Peter Tobin (pedophile and child killer)
Dennis Neilson (necrophilia and homosexual killer)

hard with serial killers to restrict a time period as sometimes it comes in bouts and can span over several years, even decades. as in the case of Peter Tobin who they now suspect was Bible John. Well, an interesting serial killer I think you should feature is the Zodiac back on 60s, 70s. He was never caught, so no one knows if he's dead or not... he could be still out there today. He literally taunted the police by giving them hints to his identity in cryptic puzzle that were nearly impossible to solve.
Good by Beth and do please kiss Belmont Shore for me and specifically Polly coffee house my favorite hangout .
