ET has obtained newly unsealed warrant papers related to searches of Dr. Conrad Murray's premises in Las Vegas.

The documents, just released by a Nevada judge, are tied to July 28 raids on Murray's home, office and storage unit in Las Vegas. Property taken in the searches included computer hard-drive images, a phone message book, a CD, binders and miscellaneous paperwork.

The judge has chosen not to unseal documents pertaining to an August 11 search of a pharmacy where Murray allegedly purchased the sleeping drug propofol, explaining that releasing those papers now "could compromise the Los Angeles Police Department's ongoing investigation into the homicide of Michael Jackson," reports the Associated Press.

The judge ordered that a hearing take place on Nov. 18 to decide if that warrant should remain sealed.
