The docs -- opposing Oksana's motion to limit the Sheriff's access to material in her computer -- state, "Evidence obtained from the Hard Drive would be used in a forthcoming criminal prosecution when Detective Wagner's findings are presented to the District Attorney's Office."

In opposing Oksana's motion, the Sheriff's Department claims it needs to do a thorough search of Oksana's computer because, "It is common for evidence to be found on a suspect's computer and hidden or mis-labeled in a particular computer file."

Arguments on the search warrant will be heard today at 1:30 PM PT, and we'll be there.
