In the video below, Danna de Groot addresses the death of her brother Peter, who was shot and killed in a standoff with RCMP officers in Slocan, B.C. last week.
"The officers on the scene had to have had a complete and utter disregard for his life, or were able to have taken the time to try to save him," his sister said on Monday in Vancouver. "He was judged unworthy to live and he was randomly given the death penalty for no good reason. In short, we are outraged.
"He was killed for being himself. This is the first time in our lives that we've been ashamed to be Canadian."
Peter de Groot had been the subject of a four-day manhunt, after he reportedly traded gunfire with officers on Thursday, October 9, 2014.
He was killed the following Monday, October 13.
In her statement, Danna said her brother was "executed" by the RCMP.
