Surrey Six investigators appeal heading to Supreme Court of Canada

Canada's highest court has agreed to hear an appeal involving four RCMP officers who investigatedthe so-called Surrey Sixmurders in Surrey, B.C.

The Supreme Court of Canada has ruled it will hear special prosecutor Chris Considine's appeals of a 2015 ruling from the B.C. Supreme Court and a 2017 decision from the B.C. Court of Appeal.

Court-imposed bans prohibit the release of details but the high court says the matters relate to allegations that fourRCMPofficers involved in the murder investigation engaged in inappropriate conduct while managing a protected witness.

RCMP officers DerekBrassingtonand Paul Johnston, DavidAttewand DannyMichaudface charges including breach of trust, obstruction of justice and fraud.

These charges laid in 2011 stem from the investigation of thegang-related murders of sixmen, including two innocent bystanders, in a Surreyhigh risein October 2007.

The trial for the four men was expected to begin in 2013, but has been delayed repeatedly.
