Photos by Serial Killer (51 pics)
Rodney Alacala (66) is also known as a "dating game killer" because of an appearance as a bachelor on that show.
He was arrested in 1979 and convicted for murdering of four women and a 12 year old girl in the West Coast states.
Now he is on death row in California.
But police thinks that he may have killed more than 100 women.
These photos were found in killer's locker that he rented in Seattle up until his arrest.
Some of these people could be the unknown victims of Rodney Alcala,
who lured his victims with a click of his camera. He asked them to pose for pictures.
The NYPD is asking the public to help with identifying hundreds of photos taken by a convicted serial killer.
