The sister of the man shot by the RCMP in Prince George says he was a decorated veteran, struggling with post-traumatic stress.

40-year old Greg Matters was killed Monday night, after a long stand-off with the mounties.

His sister Tracey says she has confidence in the investigation, but also has serious questions.

"Why was it necessary to use lethal force on a man, on his own property, who didn't have a firearm? Why wasn't my brother allowed to talk to his doctor, his mother, or family friends during the stand-off... when this was requested?"

A Prince George newspaper reports matters had been sending them e-mails, detailing his struggles with both his illness, and the police.

The new "Independent Investigation Office" remains on-scene.
