Willene Wah Ying Chong, 76, was killed early on September 11, 2008, when an arsonist deliberately set fire to the East Vancouver home where she had lived for more than three decades. She was asleep in the house at 2781 East 55th Avenue when the blaze began; her son Daniel, who lived with her, broke a basement window and was seriously injured trying to reach her but could not get to her before she died. Vancouver police classified her death as a homicide.

Investigators concluded the fire was intentional and apparently connected to a string of deliberately set fires in the Killarney-area that morning, including a burning portable toilet, items set alight on Kerr Street, a hedge fire on Lancaster Street, and a fire behind a house under construction on East 54th Avenue. Police sought information about a group of young people seen in the area but have not publicly identified any charged suspect. A $10,000 reward was offered and later renewed; the Vancouver Police Department lists the case as an ongoing cold case.

Does anyone have information about activity in the Killarney area just after 5 a.m. on September 11, 2008, that could help investigators?
