The man, who has not been named, decided to take a sunset stroll on the beach around 8:30 p.m. PT on May 30, but when returned home, he was dazed and confused, with a small head wound.
When asked about it, he could not provide any details of what had happened. He became unresponsive the following day and was taken to hospital with brain bleed. By June 4, he had died.
"The investigation is definitely going in the direction of this appearing to have been some kind of accident," says Const. Montague.
"But [it's] too early to conclude anything."
Cyclists, drone enthusiasts sought
The Vancouver Police Department say they have video of the man leaving his building and believe his mysterious and fatal injury may have happened on May 30, but it could also have happened a day or two prior.
"We also have additional video from businesses and apartment buildings, that have given us a fairly good timeline," said Const. Brian Montague.
"But we aren't releasing them because we want witnesses to give us first hand accounts."
Police say they have extensively canvassed the Kitsilano area, and some people have come forward, but they are also urging other possible witnesses, seen on the video they have gathered, to contact police.
Police say those witnesses include:- two female cyclists who, on or before May 30, are believed to have helped the man off the road along West 1st Avenue near Yew Street
- two women, described as Asian, who appear to speak with the man and let him into his building on May 30 at 9:50 p.m.
- a group of men and women, described as Asian and in their early 20s, flying a drone in the area of Kits Beach near Cornwall and Yew Street and the parking lot
The VPD says that these individuals are not suspects.
Anyone with information is asked to call the Vancouver Police Major Crime Section at 604-717-2541.
