Ashley Machiskinic fell five floors to her death from the Regent Hotel on East Hastings Street Sept. 15, 2010, in an incident that some community workers felt was likely a homicide.
Outreach worker and former Vancouver police officer Dave Dickson knew Ashley Machiskinic well and said Friday it will probably never be known for certain why the 22-year-old Saskatchewan native died.
But Dickson has his theories.
"I still don't believe for a second she jumped out that window," he said.
After her death, Machiskinic’s friends accused police of ignoring evidence that she didn't commit suicide.
At a demonstration outside the Main Street police station in October 2010, some protesters alleged Machiskinic was pushed out the window for failing to pay a drug debt.
But the report from coroner Lisa Graham, obtained by CBC News, said several people were interviewed by police, including some who were alleged to wish her harm
Video surveillance yielded no incriminating data and both Machiskinic's body and her room showed no signs of a struggle.
The woman had consumed large amounts of cocaine and had been drinking alcohol, toxicology tests showed.
Dickson said he feels for investigators.
"To be fair to them, they can't take the next step until they've got somebody that steps up to the plate and says they were in the room and actually seen something."
The police investigation remains open.
