Testifying before Pickton's first-degree murder trial in New Westminster Thursday, defence witness Bill Malone said the visitors included friends, workers, strangers and thieves, and that many had virtually unlimited access to the trailer where Pickton lived.

In fact, he said, the locks to the trailer were broken so often that efforts to lock the home were abandoned.

Malone told the B.C. Supreme Court that the visitors included Lynn Ellingsen, Dinah Taylor and Pat Casanova.

All three were arrested in connection with the murders of sex-trade workers from Vancouver's Downtown Eastside, but were never charged.

Pickton is on trial for the deaths of six women who went missing from the area: Sereena Abotsway, Mona Wilson, Andrea Joesbury, Brenda Wolfe, Marnie Frey and Georgina Papin.

Pickton, who has pleaded not guilty, faces a total of 26 counts of first-degree murder in connection with the disappearances and deaths of women from Vancouver's Downtown Eastside. Six of the charges are being handled at the current trial, which began in January, while the other 20 charges are expected to be dealt with at a subsequent trial.

The prosecution wrapped up its case last month after calling roughly 100 witnesses.
