Detectives found large quantities of general anesthetic and dozens of tubes of skin-whitening creams in Michael Jackson's home after the singer's death, search warrants unsealed Friday show. Investigators went to Jackson's rented mansion June 29 following a lengthy interview with his personal physician, Dr. Conrad Murray, who told them he had placed a medical bag in a cupboard in a closet. During their search, detectives found 19 tubes of hydroquinone and 18 tubes of Benoquin, both of which are commonly used in the treatment of a skin condition Jackson had called vitiligo. The disease creates patches of de-pigmented skin, and creams can be used to lighten skin that has retained its color to give a more even appearance. The discovery of medical creams in Jackson's home dovetails with an odd remark Murray reportedly made soon after Jackson's death. According to police statements, Jackson's personal assistant, Michael Amir Williams, told detectives, Murray told him he wanted to return to Jackson's house “so that he could pick up some cream that Mr. Jackson has so that the world wouldn't find out about it.”
