The B.C. Crown says they anticipate staying the remaining 20 charges against serial killer Robert Pickton after the Supreme Court of Canada rejected his appeal.

Pickton was convicted in December 2007 for the murders of six Vancouver women.

He appealed his conviction all the way to the high court but today the court rejected his request for a new trial.

Crown spokesman Neil MacKenzie says Pickton is serving a life sentence with no possibility of parole for 25 years -- the maximum allowed under the law.

MacKenzie says the Crown expects to take steps in the "near future" to formally discontinue the remaining prosecutions.

He says it has been a long process for the families of the victims and he hopes today's decision brings them some comfort and closure.
