Calgary police's homicide detectives are investigating the death of a man found shot in a Hillhurst alley.

Jordan Moore, 34, died Tuesday in hospital. Police have not said what they believe led to his death.

His family, however, says he was out for a "typical evening walk" that turned fatal.

"Though details are limited due to the ongoing police investigation, what we have been advised of is that while on his walk, Jordan saw an altercation and intervene[d] on behalf of someone in need," his brother, Jason Moore, said in a statement to CBC News Wednesday.

"During the altercation, he was shot. We were told that Jordan acted in an extremely noble and brave manner."

Moore was active and an avid long-boarder who regularly took long rides and walks around the city, his brother said.
