An American blood spatter expert did not review better-quality photos of bloodstains found in the motorhome belonging to Robert William Pickton in Port Coquitlam, B.C., jurors heard Wednesday.

Jon Nordby underwent cross-examination by the Crown at the B.C. Supreme Court in New Westminster, where Pickton is on trial for the killings of six women between 1997 and 2001: Sereena Abotsway, Mona Wilson, Andrea Joesbury, Brenda Wolfe, Marnie Frey and Georgina Papin.

Throughout his testimony, Nordby said the roughly 100 police photos he was dealing with were so bad he was unable to draw any conclusions from them.
 
Jurors at the beginning of the trial heard from the Crown's blood spatter expert, who described the scene in the motorhome as a "blood letting."  Jurors then heard that numerous items within the motorhome were positive for blood, and contained DNA matching Mona Wilson.

The Crown asked Nordby Wednesday if he knew police took 2,668 photos of the motorhome that were all disclosed to the defence. 

Nordby replied he did not, but later added he was given everything the defence had, and that he was only to deal with the photos that were already before the jury as evidence.

Nordby said as a result he "didn't bother" with the others.

The Crown presented Nordby with four more photos, which he agreed were better photos of certain stains.

But Nordby maintained his conclusion that he did not believe a major blood-letting event occurred in the motorhome and that blood found there may have come from different occasions.

"Blood stain pattern analysis, in my opinion, can't be pushed that hard." Nordby said.

"That is we can't do what is done on television and say … that a left-handed stranger weighing 300 pounds brought the knife up four times and came down narrowly missing the cup of cider, etc. You can't do that. It just doesn't happen," he said.

Pickton is facing 26 counts of first-degree murder in total in connection with the deaths of women from Vancouver's Downtown Eastside. He is currently on trial for six of the deaths and will be tried on the remaining 20 later.

He has pleaded not guilty to all charges.
