-LRB- CNN -RRB- -- Texas authorities released court documents Thursday detailing the items seized from the medical office and storage unit of Dr. Conrad Murray , the cardiologist who was with Michael Jackson when he fell ill and died on June 25 . Dr. Conrad Murray 's office was searched Wednesday for `` evidence of the offense of manslaughter . '' Detectives searched both sites in Houston on Wednesday for `` evidence of the offense of manslaughter , '' according to court documents . Murray 's attorney confirmed the search Wednesday . Among the items removed from Murray 's office were a computer ; 27 tablets of Phentermine , a prescription-strength appetite suppressant ; 1 tablet of clonazepam , an anti-anxiety medication ; and some Rolodex cards . From Murray 's storage unit , authorities removed two computer hard drives ; an `` important contact list '' ; a suspension notice from Houston 's Doctors Hospital ; notices from the Internal Revenue Service ; and a list of medical and hospital documents . Jackson 's former nurse , Cherilyn Lee , was also approached on Wednesday by investigators who wanted copies of medical files she had on the singer , Lee told CNN 's Nancy Grace . Lee said she handed over the files to officials with the coroner 's office . Ed Chernoff , a Houston lawyer hired by Murray soon after Jackson 's death , confirmed that Los Angeles Police detectives and federal Drug Enforcement Administration agents used a search warrant to enter Murray 's office in northeast Houston on Wednesday morning . `` The search warrant authorized law enforcement to search for and seize items , including documents , they believed constituted evidence of the offense of manslaughter , '' Chernoff said in a written statement Wednesday . Chernoff said members of Murray 's legal team were at the medical office during the search , which he said `` was conducted by members of the DEA , two robbery-homicide detectives from the Los Angeles Police Department and Houston Police officers . '' `` Law enforcement concluded their search around 12:30 p.m. and left with a forensic image of a business computer hard drive and 21 documents . None of the documents taken had previously been requested by law enforcement or the L.A. coroner 's office , '' Chernoff said . Tammy Kidd , a spokeswoman at Chernoff 's office , said the search `` was absolutely a surprise to us , because we 've had open lines of communication this whole time . '' `` Based on Dr. Murray 's minute-by-minute and item-by-item description of Michael Jackson 's last days , he should not be a target of criminal charges , '' Chernoff said Tuesday . `` Dr. Murray was the last doctor standing when Michael Jackson died and it seems all the fury is directed toward him . '' Los Angeles investigators have interviewed Murray twice , Chernoff said . A third interview has not been scheduled , he said . Police impounded his car , which had been parked at Jackson 's Holmby Hills home , the night after Jackson 's death . It was released to Murray several days later . `` Dr. Murray is frustrated by negative and often erroneous media reports . He has to walk around 24-7 with a bodyguard , '' Chernoff said . `` He ca n't operate his practice . He ca n't go to work because he is harassed no matter where he goes . '' At least two investigations are under way into Jackson 's death . The Los Angeles County coroner is waiting for toxicology results to determine a cause of death , while the city Police Department , with assistance from the Drug Enforcement Administration , is looking at the possibility of criminal charges . A coroner 's office spokesman said the autopsy findings could be released in the next week or more . Los Angeles Police Chief William Bratton told CNN he would wait for the coroner to determine the exact cause of Jackson 's death . `` And based on those , we will have an idea of what it is we are dealing -LRB- with -RRB- : Are we dealing with a homicide , or are we dealing with an accidental overdose ? '' he said . CNN 's Alan Duke , Ted Rowlands and Randi Kaye contributed to this report .
