Hundreds of items were seized from two cars on property where the brother of accused serial killer Robert William Pickton lived, but few have been sent to a police lab for testing, defence lawyers suggested Monday.

RCMP Sgt. Peter Morris testified at the B.C. Supreme Court in New Westminster that roughly 700 items were taken from the cars on Dave Pickton's land. They included women's clothing, condoms, makeup and drug paraphernalia, he said.

The jury heard that police seized about 200 items from a grey Cadillac and about 500 from an Oldsmobile Cutlass. Defence lawyers suggested 29 of the hundreds of items taken from the two vehicles have been sent to a police lab for testing.

Dennis Thrift, case manager for the missing women's task force at the RCMP's forensic lab, couldn't confirm how many of the items from the cars he had received. Justice James Williams instructed him to return to court with the correct answers.

Dave Pickton lived in the main farmhouse on the southern end of the family-owned property, which included the so-called "Piggy's Palace," a large metal building notorious in the neighbourhood for parties. His older brother, Robert, lived in a trailer on the other end of the property, which included the pig slaughterhouse.

Robert Pickton is being tried on first-degree murder charges in connection with the deaths of six women who disappeared from Vancouver's Downtown Eastside. He faces 20 other murder charges that will be dealt with at another trial later. He has pleaded not guilty to all 26 charges.

Earlier this month, the jury heard that Dave Pickton had been under RCMP surveillance as late as 2005. He has never been arrested or charged in connection with the police investigation into the missing women.

This trial, which began the third week of January and is expected to last a year, is focusing on the murders of Mona Wilson, Sereena Abotsway, Andrea Joesbury, Brenda Wolfe, Georgina Papin and Marnie Frey.
