Los Angeles ( CNN ) -- Jurors in the trial of Michael Jackson 's doctor worked for more than seven hours Friday before telling the judge that they had not reached a verdict and were ready to go home for the weekend . The seven men and five women deciding the fate of Dr. Conrad Murray , who is charged with involuntary manslaughter in the 2009 death of the pop icon , will resume deliberations Monday morning . Katherine and Joe Jackson , the parents of the Jackson family , were so anxious for a verdict that they spent Friday afternoon in a hotel near the courthouse so they could get there quickly . Dozens of Jackson fans filled the plaza outside of the downtown Los Angeles County courthouse , shouting slogans , waving signs and sometimes arguing with Murray supporters . The jury heard from 49 witnesses over 23 days , including Murray 's girlfriends and patients , Jackson 's former employees , investigators , and medical experts for each side . Prosecutor David Walgren told them Thursday the evidence that Murray caused Jackson 's death is `` overwhelming '' and `` abundantly clear , '' while defense lawyer Ed Chernoff argued no crime was committed . `` If it were anybody else but Michael Jackson , would this doctor be here today ? '' Chernoff asked , saying it 's a negligence case that should instead be heard by the state medical board . `` He was just a little fish in a big , dirty pond , '' Chernoff said , pointing the finger at other doctors who treated Jackson , and at Jackson himself . The singer 's death on June 25 , 2009 , was caused by acute propofol intoxication in combination with two sedatives , the Los Angeles County coroner ruled . Jurors must decide if the overdose of the surgical anesthetic propofol was infused into Jackson 's blood by a steady IV drip , as the prosecution contends , or if Jackson injected himself with a syringe left nearby by Murray , as the defense argues . Prosecutors argue that Murray 's use of propofol in Jackson 's home to treat his insomnia was so reckless it was criminally negligent . `` Conrad Murray left Prince , Paris and Blanket without a father , '' Walgren said . `` For them , this case does n't end today , or tomorrow . For Michael 's children , this case will go on forever , because they do not have a father . They do not have a father because of the actions of Conrad Murray . '' Walgren argued that until Jackson 's death , no one ever heard of propofol being in a home every night to put someone to sleep . He called it `` a pharmaceutical experiment on Michael Jackson ... an obscene experiment . '' The defense contends Jackson self-administered the fatal overdose of drugs in a desperate search for sleep without Murray 's knowing . `` What they 're really asking you to do is to convict Dr. Murray for the actions of Michael Jackson , '' Chernoff said . After Chernoff finished his arguments , Walgren attacked the defense for trying to blame `` everybody but Conrad Murray , poor Conrad Murray . '' `` If allowed more time to argue , I am sure they would find a way to blame Michael 's son , Prince , '' Walgren said in his rebuttal . Walgren painted Murray as a selfish doctor who agreed to take $ 150,000 a month to give Jackson nightly infusions of propofol in his home , something an ethical doctor would never do because of the dangers . While Jackson was hooked up to a constant intravenous drip of propofol , Murray was not paying attention , the prosecutor said . Telephone records and testimony showed he was talking to Sade Anding , a Houston cocktail waitress , when he realized Jackson had stopped breathing . `` What was so important to Conrad Murray that he had to call Sade Anding at that time ? What was so important to this doctor that he needed to call one of his female friends in Houston ? What was so pressing that he just could n't care for Michael Jackson , that he had to call Sade Anding ? '' It will never be known how long Jackson had not been breathing when Murray dropped the phone in the middle of his conversation with Anding , the prosecutor said . `` Was Conrad Murray in another room ? Did Michael Jackson yell out for help ? Did he gasp ? Did he choke ? Were there sounds ? We do n't know and we 'll never know , because of the neglect and negligence of Conrad Murray . '' Walgren questioned why Murray waited at least 20 minutes after he found Jackson was not breathing before he asked a security guard call for an ambulance . `` To speak to a 911 operator was the only hope of Michael Jackson being revived to see another day , '' Walgren said . Paramedics arrived just four minutes after the call , but too late to save Jackson , he said . Chernoff argued that Murray depended on chef Kai Chase to send up a security guard while he was trying to revive Jackson , but she only sent son Prince . When Murray spoke with police two days after Jackson 's death , it was `` to get ahead of the story , '' because he knew there would be toxicology reports showing he died from propofol and sedatives , Walgren said . `` Unfortunately , his version does n't match up with the evidence , the phone records , the e-mails , but he knew what toxicology findings would show , '' Walgren said . Jurors heard from two anesthesiology experts who offered competing theories , Dr. Steven Shafer for the prosecution and Dr. Paul White for the defense . Walgren attacked White for his determination `` to find a theory or way to blame it on Michael Jackson . '' White testified that the levels of propofol and sedatives found in Jackson 's stomach , blood and urine during the autopsy convinced him that Jackson swallowed a large does of lorazepam and later gave himself a rapid injection of propofol , which led to his death . `` What you were presented from Dr. White was junk science , '' Walgren said . Chernoff defended his expert and attacked Shafer , saying he was `` not a scientist ; he was an advocate . He was trying to prove a point ; he was trying to prove a case . '' `` Dr. White knows more about propofol than Dr. Shafer will ever , ever know , '' Chernoff said . Shafer testified that the `` only scenario '' in Jackson 's death was one involving an IV drip system infusing a steady flow of propofol into Jackson over several hours before his death . Chernoff argued that the prosecution fabricated the theory because they `` desperately needed a drip , '' because `` without a drip , what Dr. Murray gave Michael Jackson would not have harmed him . '' `` If Dr. Murray did what he said he did , there was no danger to Michael Jackson , '' Chernoff said . `` Michael Jackson was not going to die and it does n't matter if you leave the room and go outside and play basketball . '' Chernoff attacked the credibility of Alberto Alvarez , Jackson 's former bodyguard , who testified that he saw a propofol bottle inside an empty saline bag suspended on an IV stand by Jackson 's bed . Alvarez waited two months after Jackson 's death to tell the story , Chernoff said . `` All of a sudden , his story becomes monumentally more compelling and more valuable , '' Chernoff said . Alvarez acknowledged he turned down a $ 500,000 offer for an interview , Chernoff said . `` Do you honestly believe that Alberto Alvarez is not going to cash in ? '' Alavarez , who placed the 911 call from Jackson 's bedroom , also testified he helped remove Jackson from the bed and performed CPR on him , but a paramedic contradicted that testimony . Investigators who found the cut saline bag and propofol bottle never photographed them together or document the bottle being inside the bag , Chernoff said . The `` bottle in a bag '' theory was even less believable because the propofol bottle had a plastic strip attached to it so it could be hung from an IV stand , he said . That strip was never used , both sides agreed . `` Dr. Murray did n't have to go through the ridiculous , absurd step of cutting a bag , propping it up into a cut IV bag , hanging it up where it could fall , '' Chernoff said . Murray , if convicted , faces up to four years in prison and the loss of his medical license .
