Rostam Poulad-Noshiravan, 69, had lived on the 4000 block St. Georges Avenue in the Upper Lonsdale neighbourhood for more than 20 years, neighbours told CBC News. He had a wife and raised his family there, they said.

Sgt. Bari Emam, with the Lower Mainland's Integrated Homicide Investigation Team identified Poulad-Noshiravan as the homicide victim — North Vancouver's first in 2013 — and issued a plea for tips Sunday afternoon.

"Mr. Poulad-Noshiravan was not known to police," Emam said in a written statement. "The victim’s family are shocked by this incident and also hoping that tips from the public and those who may know something can assist the investigators in getting some answers."

Witnesses in Poulad-Noshiravan's neighbourhood saw a vehicle speed away from the street after gunshots were heard, at approximately 1:18 p.m. PT.

Within minutes, police on the North Shore moved to begin shutting down traffic across both the Lions Gate and Ironworkers Memorial bridges in an attempt to apprehend the shooter. No suspects were located or arrested.

Emam said IHIT believes the suspect vehicle is either a grey or silver import-style car.

"Anyone who may have seen this car is urged to contact IHIT if they have more information about the car or its occupant(s)," Emam wrote.
