The trial of Robert Pickton, accused of killing 27 women, begins Monday in the B.C. Supreme Court in New Westminster, B.C.

His lawyer has said he is expected to plead not guilty.

The proceedings will start with arguments over what evidence can be admitted, a process that's expected to take several months alone. Reporters are not allowed to disclose material presented in these arguments because it may be ruled inadmissible.

Pickton has been in jail for nearly four years.

Before he was arrested in February 2002, Pickton lived on a pig farm in Port Coquitlam, just east of Vancouver.

Pickton was originally charged with 15 counts, but another 12 charges were laid in May 2005.

Most of the victims were sex-trade workers from Vancouver's Downtown Eastside.
