Katherine Jackson: Michael's mother, 82, was deposed for nine hours over three days by AEG Live lawyers. As the guardian of her son's three children, she is a plaintiff in the wrongful death lawsuit against the company that promoted Michael Jackson's comeback concerts.
Kenny Ortega: He was chosen by Michael Jackson and AEG Live to direct and choreograph the "This Is It" shows. Ortega, who choreographed for Jackson's "Dangerous" and "HIStory" tours, testified at Dr. Conrad Murray's criminal trial that "Jackson was frail" at a rehearsal days before his death.
Dr. Conrad Murray: He was Michael Jackson's personal physician in the two months before his death, giving him nightly infusions of the surgical anesthetic that the coroner ruled led to his death. Murray, who is appealing his involuntary manslaughter conviction, has sworn that he would invoke his Fifth Amendment protection from self-incrimination and refused to testify in the civil trial. There is a chance that Murray will be brought into court from jail to testify outside the presence of the jury to allow the judge to determine if he would be ordered to testify.
Joe Jackson: Michael's father, 84, is on the witness list for the trial and may testify. The Jackson family patriarch, who lives in Las Vegas separately from his wife, has suffered several ministrokes in the last year, which some close to him say have affected him.
Prince Jackson: Michael's oldest son is considered a key witness in the Jacksons' case against AEG Live, since he is expected to testify about what his father told him about the concert promoter in the last days of his life. Prince, who turned 16 in February, is becoming more independent -- he now has a driver's license and jobs.
Paris Jackson: Michael's daughter, who turned 15 on April 3, is on the list of witnesses and was questioned by AEG Live lawyers for several hours on March 21 about her father's death. Paris is an outspoken teen who often posts messages to her 1 million-plus Twitter followers.
Blanket Jackson: Although AEG Live asked the judge to order Blanket, 11, to sit for a deposition, and he is one of the four plaintiffs suing them, Michael's youngest son will not be a witness in the trial. His doctor submitted a note to the court saying it would be "medically detrimental" to the child.
Randy Phillips: He's president of AEG Live, the concert promoter that contracted with Michael Jackson for his "This Is It" comeback shows set to start in London in July 2009. The Jackson lawsuit says Phillips supervised Dr. Conrad Murray's treatment of Jackson in the weeks before his death, making the company liable for damages. E-mails between Phillips and other executives showed they were worried about Jackson's missed rehearsals and sought Murray's help getting him ready.
Kevin Boyle: The Los Angeles personal injury lawyer is leading the Jackson team of at least six attorneys in the wrongful death suit against AEG Live. One of his notable cases was a large settlement with Boeing on behalf of two soldiers injured when their helicopter malfunctioned and crashed in Iraq.
Perry Sanders, Jr.: Katherine Jackson's personal lawyer is helping steer the Jackson matriarch through her relations with her son's estate, probate court and the wrongful death suit. He is also known for representing the family of Biggie Smalls in their suit against the city of Los Angeles over the rapper's death investigation.
Marvin Putnam: He's the lead lawyer for AEG Live, defending against the wrongful death suit. The primary focus of his legal practice is "media in defense of their First Amendment rights," according to his official biography.
Philip Anschutz: The billionaire owner of AEG, parent company of AEG Live, is on the Jacksons' witness list. He is the force behind the effort to build a football stadium in downtown Los Angeles to lure a National Football League team to the city. He recently pulled his company off the market after trying to sell it for $8 billion.
Tim Leiweke: He was recently fired as AEG's president as Philip Anschutz announced he was taking a more active role in the company. The Jackson lawyers say Leiweke's e-mail exchanges with executives under him concerning Michael Jackson's health are important evidence in their case.
Paul Gongaware: The AEG Live co-CEO worked closely with Michael Jackson as he prepared for his comeback concerts. He testified at Dr. Conrad Murray's criminal trial that he contacted the physician and negotiated his hiring at the request of Jackson. AEG lawyers say it was Jackson who chose, hired and supervised Murray. Gongaware knew Jackson well, having been tour manager for the singer in previous years.
John Branca: He's one of two executors of Michael Jackson's estate. Branca was Jackson's lawyer until about seven years before his death. He said Jackson rehired him just weeks before he died.
- NEW: Lawyer for Dr. Conrad Murray lets out gasp, appears shaken
- NEW: Jurors ruled Murray was a competent doctor
- The jury said AEG had hired Murray but was not liable for Jackson's death
- Jackson died just days before his 2009 comeback tour was set to kick off
Los Angeles (CNN) -- A Los Angeles jury decided Wednesday that AEG Live hired Dr. Conrad Murray, but also concluded that the concert promoter was not liable for Michael Jackson's drug overdose death.
The jury decided that Murray was competent, so even though AEG Live hired him, it was not liable for Jackson's death and didn't owe the Jackson family millions of dollars in compensation.
The verdict brings the five-month-long trial to a close.
The jury accepted AEG Live lawyers' arguments that the company was not negligent because its executives had no way of knowing that Murray -- licensed to practice in four states and never sued for malpractice -- was a risk to Jackson. The singer was a secretive drug addict who kept even his closest relatives in the dark about his use of propofol to sleep, they contended.
Jackson's mother, Katherine, and the singer's three children sued AEG Live in 2010, arguing that the company's negligence in hiring, retaining or supervising Murray was a factor in the singer's June 25, 2009, death.
Jackson died of an overdose of the surgical anesthetic propofol, which Murray told investigators he was using to treat the singer's insomnia so he could rest for rehearsals. Murray is set to be released from jail later this month after serving two years for involuntary manslaughter.
Jackson died just days before his comeback tour -- promoted and produced by AEG Live -- was set to debut in London in the summer of 2009.
Murray's lawyer, Valerie Wass, let out a gasp when she heard the decision and was visibly shaken.
Because jurors concluded that AEG Live was not liable, they did not consider other questions on the verdict form that would have determined how much in damages the promoter would have paid Katherine, Prince, Paris and Blanket Jackson.
Jackson lead lawyer Brian Panish suggested a range between $1 billion and $2 billion to replace the earnings lost by Jackson's death at age 50 and the non-economic -- or personal -- damages from the loss of a father and son.
The damage award, however, would have been reduced by the percentage of blame jurors decided Michael Jackson shared in his death. The Jacksons lawyer suggested in closing arguments that they assign 20% of the liability to Jackson.
AEG's lawyers had contended Jackson chose Murray, who had treated him for three years as a family physician, but Jackson lawyers had argued the promoters chose to negotiate their own contract with the doctor so they could control him.
Jurors appeared engaged and entertained during the 21-week trial that included dramatic testimony by Jackson's mother, son and former wife.
