Vancouver: Investigators would like to speak with a woman who provided first aid to a stabbing victim outside a Halloween celebration at the Plaza of Nations last fall.

Shortly after 2:00 am on November 1st, police received several 9-1-1 calls about two groups of men involved in an altercation at the Plaza of Nations at 750 Pacific Boulevard. Three men suffered serious stab wounds. One of those men, 25-year-old Hansen Jia Chen from Burnaby, died from his injuries.

Before police and paramedics arrived, an unknown woman provided Hansen Chen with first-aid near the taxi stand at the front of the plaza. According to witnesses, the woman identified herself as a BCIT nursing practicum student.

Investigators are interested in speaking with the woman as a witness to the incident. So far, they have been unable to identify her, and are appealing through the media in hopes she will come forward and contact detectives at 604-717-2500.

Investigators are again requesting that anyone who may have any cell phone footage showing the area near the Plaza of Nations between 9:00 pm on October 31st and 2:00 am on November 1st, contact them at 604-717-2500.
