VANCOUVER -- The fatal shooting of longtime homeless advocate Barry Shantz by a police officer will not be referred to Crown counsel for charges, B.C.'s police watchdog said in a report released Tuesday.

In its report, B.C.'s Independent Investigations Office wrote that the use of lethal force by a member of the Lytton RCMP, which occurred after a standoff that spanned over six hours on Jan. 13, "was necessary and proportionate to the risk."

According to the report, Shantz had a loaded shotgun in his hands and was suicidal, and before he walked out the front door of his Fraser Canyon home, told Mounties he wanted to be shot six times.
