MANHATTAN — Two women have come forward to say they were photographed by serial killer Rodney Alcala after seeing their pictures in a series of photos released by the NYPD.
Judy Cole of North Carolina told police she met Alcala on the Upper West Side in 1978 and agreed to pose for him on a rooftop, the Daily News reported Thursday.
"He was very charming. I should have known better," Cole told the News.
Another woman living in California told police she thinks she’s also among the people Alcala, known as the Dating Game killer, photographed.
Police believe there could be more victims shown among the photographs. Alcala, 66, is on death row for five murders. He is a suspect in at least two other murders, both in New York.

Alcala, who studied film under Roman Polanski, lived in Greenwich Village.
More than 200 photos were released by the NYPD on Tuesday after they received the pictures from the Orange County, Calif., prosecutor’s office. California police found more than 1,000 photos in a locker owned by Alcala.
Members of the public are asked to notify the NYPD’s Crimestoppers’ Hotline at 1-800-577-TIPS if they recognize any of the individuals in the photographs.
