B.C. man's refusal to admit to sexual assault conviction sends message: lawyer

VANCOUVER - A lawyer says his client deserves compensation for lost job opportunities, mental breakdowns and post-traumatic stress disorder in the 24 years since she was sexually assaulted in Burnaby, B.C.Jason Gratl has delivered closing arguments in a civil case filed by a woman against David Pickton, who was convicted a year after the assault, in 1992.The woman is also suing Pickton, who is the brother of serial killer Robert Pickton, for unproven threats of rape and murder.Gratl says an employee and friend of Pickton's threatened the woman would be cut into pieces if she didn't leave town after Pickton groped her at a construction site where they worked.Gratl has told a jury that Pickton's refusal to admit that he has been convicted of sexual assault shows he does not know right from wrong.Robert Pickton was convicted in 2007 of six counts of second-degree murder, but David Pickton has never been accused or charged in those crimes.
