The haul includes personal photographs of Hilton, two pairs of her designer jeans and a white hat, according to law enforcement sources and a copy of a search warrant obtained by the Los Angeles Times newspaper.
Los Angeles Police Department officers, accompanied by Las Vegas Metro Police officials, also seized two stolen computers, marijuana, a Korean passport and more than $20,000 (GBP12,500) in cash.
The authorities arrested teenager Rachel Lee during the 22 October (09) raid, but Lee has not been charged with any of the burglaries.
Six other people have been charged in connection with the burglary spree that netted more than $3 million in designer clothing, accessories and jewellery between December 2008 and October 2009.
