British Columbia's police watchdog has cleared officers of criminal wrongdoing in the shooting death of a retired soldier in northern B.C. after reviewing evidence presented in a coroners inquest.

The Independent Investigations Office conducted a supplemental review after a pathologist testified Greg Matters was shot in the back, contrary to what the agency said in a report.

Greg Matters was 40 when he was killed in a police confrontation at his home outside Prince George

Richard Rosenthal of the agency says there is no new evidence suggesting any of the officers involved in the shooting death of Matters may have committed a criminal offence.

The agency says it won't refer the case to Crown counsel.

Matters, who was being treated for post-traumatic stress disorder at the time, was shot and killed by RCMP during a standoff in September 2012 outside a home he shared with his mother near Prince George.

Police went to the house to arrest Matters on a charge of assaulting his brother.
