VANCOUVER — The commissioner of the inquiry examining how police probed Vancouver's missing women cases has reacted angrily to allegations from a lawyer representing families of the victims.

Cameron Ward told the inquiry he fears the commission is enabling a police coverup because many documents haven't been disclosed and no one mentioned that the lead Vancouver police investigator in the case has written a book.

Ward says he still wants to see the unpublished book, but hasn't been given access to Det. Const. Lori Shenher's manuscript and that suggests to him police are trying to hide something.

Ward says unless the commission uses its powers to ask for that information, it will enable the police to cover their involvement in the Robert Pickton serial killer investigation.

Commissioner Wally Oppal calls the suggestion disturbing and says there's no evidence the commission is enabling a coverup.

Vancouver Police lawyer Tim Dixon says the department is at the inquiry in openness and good faith, wants all the facts to come out, and there's nothing resembling a coverup.
