Mounties investigating the hit-and-run that killed a Port Coquitlam teenager Tuesday have released surveillance video captured less than a block away from the scene in an attempt to generate new tips.

The video reveals a man parking a black truck just a few houses down from the intersection of Mary Hill and Pitt River roads, where 16-year-old Annie Leung was fatally struck at a crosswalk.

The driver is seen exiting the truck, walking around the front of the vehicle then running out of view toward the crash.

About one minute later he reappears, enters the truck and drives away southbound on Mary Hill Road.

Mounties confirm the truck matches the suspect vehicle description of a black truck with a black canopy, possibly a Ford F-150, but are only referring to the driver as a “person of interest.”

“Investigators have not identified or spoken to the man seen in the video but believe he could have important information about the critical moments immediately before and after the collision,” the RCMP said in a release.

Investigators are asking for the public’s help identifying the man, as well as two other people who were at the scene of the accident.

One is a man who administered first aid to the victim, while the other was driving a silver truck in the immediate vicinity of the collision. Mounties do not have a physical description of the driver, and say the truck is not a suspect vehicle.

“On behalf of the victim, her family and friends and everyone who has been touched by this tragedy, I am asking these three individuals, as well as anyone else with information about the collision, to contact us immediately,” RCMP Insp. Paulette Freill said.

Freill added a message for the hit-and-run driver: “It is not too late to do the right thing.”

Leung, a Grade 10 student at Riverside Secondary School, was crossing the street with a friend when she was struck sometime before 4 p.m.

She was rushed to hospital but died of her injuries on Wednesday.

Leung had been living with her family from Hong Kong.

Anyone with information on the crash is asked to call the Coquitlam RCMP Traffic Services at 604-945-1550, or Crime Stoppers at 1-800-222-8477 if they wish to remain anonymous.
