There is more DNA evidence incriminating one of Robert William Pickton's acquaintances than there is against the accused, a defence lawyer told a B.C. court on Wednesday.

Adrian Brooks continued his closing arguments in a Supreme Court in New Westminster, picking apart the murder case against Pickton. He told the court that police ignored evidence against others who may have been involved in the slayings of six women from downtown Vancouver's east side.

Pickton, a Port Coquitlam pig farmer, is charged with first-degree murder in the deaths of Sereena Abotsway, Mona Wilson, Andrea Joesbury, Brenda Wolfe, Marnie Frey and Georgina Papin. He'll face another 20 murder charges at a later date.

Brooks said DNA testing linked the deaths of some of the women, whose remains were found on the Port Coquitlam farm, to Pat Casanova, a man who often spent weekends at the farm helping to run the small pig butchering business.

Casanova was arrested in January 2003 in connection with the deaths of 15 women but after being held in custody for five to six hours, he was released without being charged.

On the first day of the trial back in January, the Crown said Pickton was uniquely positioned to commit the murders, having the means, expertise and opportunity.
 
Brooks said on Wednesday that Casanova had the same means, the same expertise, and opportunity — having reluctantly admitted on the witness stand that he had sex with Joesbury and other sex-trade workers on the Pickton property.

"What we have as we deal with this evidence of Mr. Casanova is it associates him to sites, particular places … (and) to women," Brooks said.
 
"It does so in a way that I suggest to you is very important to take into account. Take into account please how it is stronger than the evidence against Mr. Pickton."

Brooks also pointed an accusing finger at Dave Pickton, brother of the accused. Among other things, Brooks spoke of pills found in his bedroom, noting that evidence showed the same drug was found in Joesbury's body.

The defence lawyer also mentioned Dinah Taylor, a friend of Robert Pickton's, who was overheard saying she wanted to kill Joesbury. Taylor also used makeup that belonged to some of the victims.

Neither Dave Pickton nor Taylor were called to testify at the trial, Brooks pointed out.

He told the jury: "You're not getting the full picture" from the Crown.

The defence is expected to wrap up its final arguments on Thursday.
