A serial killer who avoided detection for 20 years - until he voluntarily gave a DNA sample - was sentenced Tuesday to 75 years to life in prison.

Francisco Acevedo, 43, had been convicted of murdering three women in Yonkers between 1989 and 1996.

"These were monstrous crimes by a cruel and inhuman individual," said Westchester County Judge Barbara Zambelli, who combined three maximum sentences.
