The first search of Michael Jackson’s bedroom a day after his death found marijuana, skin-bleaching and hair-growing ointments, anti-insomnia pills and empty bottles of several anti-anxiety drugs, according to court documents unsealed Thursday. A substance initially suspected to be tar heroin proved not to be a narcotic, according to a source with knowledge of the investigation. An affidavit, written by Los Angeles Detective Orlando Martinez, was used to outline probable cause for a warrant to search Jackson’s Holmby Hills, California, home on June 26.
