Crown has released photo and video evidence in the trial of a B.C. man accused in the gruesome killing of a Vancouver couple.
Rocky Rambo Wei Nam Kam has pleaded not guilty to two counts of first-degree murder in the deaths of 68-year-old Richard Jones and 64-year-old Dianna Mah-Jones at their home near West 64th Avenue and Hudson Street on Sept. 27, 2017.

In its opening statements, Crown told the court that it would prove that a hatchet and knife found at the scene were used by Kam to kill the couple, that Kam’s DNA was found under Mah-Jones’ fingernails and that her DNA was found on his glasses.
Crown’s theory is that Kam purchased a hatchet and gloves in the days leading up to the double-murder with the intent of killing someone, but that he had no relationship with the victims.
On Tuesday, Crown played video evidence to the court that shows a man purchasing a baseball cap, gloves and a hatchet at Canadian Tire.
Vancouver police Det. Simon Cracknell testified that the man seen in the video is Kam.

For the first time, following an application to the court from several media outlets, including Global News, the public is also seeing images of evidence from the scene of the murders.
Photographs include a bloody hatchet that Crown says had the victims’ DNA on it, and which prosecutors allege is the same item Kam purchased in the video.

The court has already heard from Vancouver police officers who discovered the murdered couple stacked in a shower stall, and who described the bloody scene as “catastrophic.”
Police testified that there was no indication anything had been stolen from the home, suggesting robbery was not the motive.

Prosecutor Daniel Mulligan told the court that Richard Jones suffered 103 “sharp force injuries” while Maj-Jones suffered “blood loss from a laceration to the carotid artery.”
The court has also heard from Kam’s former roommate Darby Morton, who testified that he’d never seen the accused drinking or doing drugs, and that he appeared to come from a normal family.
Under cross-examination, Morton told the court that Kam did appear “kind of depressed.”
