Convicted child-killer Clifford Olson is dying of cancer, Vancouver radio station CKNW reported Wednesday. The mother of one of Olson’s victims told the station that Corrections Canada told her the man may have days to live. Olson is serving 11 concurrent life sentences. He pleaded guilty to a series of murders in B.C in 1981. Sharon Rosenfeldt, whose 16-year-old son was one of Olson’s victim, says she was told Olson has been transferred from prison to a hospital in Laval, Que.
