Judge Michael Pastor warned everyone in the courtroom to make no sound when the verdict was read, but with the pronouncement of the jury's decision, some could not suppress their emotions, and shrieks were heard in the courtroom.
Murray, 58, was remanded into the custody of the sheriff's department without bail until he is sentenced on Nov. 29. He showed no emotion when the guilty verdict was read and remained stone-faced while he was led out by deputies in handcuffs.
After the verdict was read, the Jackson family hugged prosecutors, and Katherine Jackson, mother of the 50-year-old pop star, was seen kissing Deputy District Attorney David Walgren on the cheek.
Jackson fans outside the downtown courthouse erupted in cheers. Some sang "Beat It" and held signs that read "Guilty," "Killer," and "Justice for Michael." Drivers honked their horns.
Murray's defense team left the courthouse making few comments. Defense attorney Michael Flanagan said, "Certainly there will be an appeal."
The seven men and five women deliberated for 8 hours and 38 minutes before reaching a verdict. They had been sifting through six weeks of evidence and witness testimony.
"Feels worse in some ways because nothing is going to bring my brother back," Rebbie Jackson said shortly after the verdict was read.
Los Angeles District Attorney Steve Cooley praised investigators, prosecutors and the jury for their work in the case.
"We are gratified that the jury saw that the overwhelming evidence in this case led to just one conclusion: that Dr. Conrad Murray is guilty of involuntary manslaughter in the death of Michael Jackson," Cooley said.
Walgren also made a brief statement after Cooley, thanking Pastor and the jury for "being so conscientious in their duties."
"I just thank the jury, and our sympathies go out to the Jackson family at this time for the loss that they have suffered, not a pop icon but a son and a brother. And I think that's most important to keep in mind today," Walgren said.
Jackson's family, including Katherine, Joe, Randy, Rebbie, La Toya and Jermaine, were at the courthouse for the reading of the verdict. Kathy and Richard Hilton were also seen with the Jackson family.Janet Jackson was not present because she was in Sydney to perform at the Sydney Opera House.
"Wonderful, absolutely, justice was served, Michael was watching over us," La Toya Jackson said as she walked out of the courthouse.The jury was not asked to determine whether Murray actually gave Jackson the fatal dose, only whether he was primarily responsible for the singer's death.
The jury decided Murray was responsible for the fatal dose of the powerful anesthetic propofol that killed Jackson. The defense had contended Jackson gave himself the fatal dose.
Murray faces four years in prison and losing his medical license when he is sentenced.
Jackson was about to mount a series of heavily promoted concerts in London that he hoped would cement a legacy larger than that of Elvis Presley or the Beatles.
"We have to be phenomenal," Jackson said about his "This Is It" concerts in London. "When people leave this show, when people leave my show, I want them to say, `I've never seen nothing like this in my life. Go. Go. I've never seen nothing like this. Go. It's amazing. He's the greatest entertainer in the world."'
