What is the cause of the death of Michael Jackson?

The Los Angeles County Coroner’s office classified Jackson’s death as a homicide on August 28, 2009, concluding that the singer died from acute propofol intoxication with a contributory benzodiazepine effect (Wikipedia (the online encyclopedia)). The 51-page autopsy report, reviewed by CNN (news organization), confirmed that propofol—a powerful anesthetic never intended for home use—was the primary cause, with three other sedatives (lorazepam, midazolam, and diazepam) contributing.

Toxicology findings

The toxicology report, detailed in The New York Times (newspaper), showed that Jackson’s blood contained a concentration of propofol consistent with what would be used for general anesthesia in a hospital operating room. A forensic anesthesiology study published by Hilaris Publisher (forensic medicine journal) noted that the combination of propofol and benzodiazepines caused respiratory depression and cardiac arrest.

Role of Dr. Conrad Murray

Dr. Conrad Murray, Jackson’s personal physician, admitted in court testimony that he had been administering propofol nightly for about six weeks to treat Jackson’s insomnia (People magazine). On the morning of June 25, Murray gave Jackson a series of sedatives—Valium at 1:30 a.m., lorazepam at 2 a.m., and midazolam at 3 a.m., 5 a.m., and 7:30 a.m.—before administering 25 mg of propofol diluted with lidocaine at around 10:40 a.m. (ABC News (television network)).

What was Michael Jackson doing before he died?

In the weeks leading up to his death, Jackson was deep in preparations for his comeback tour, “This Is It,” which was scheduled to begin in London on July 13, 2009. He had been rehearsing intensively at the Staples Center in Los Angeles.

Preparations for This Is It tour

Jackson was reportedly in good spirits despite the physical demands. He had been working with choreographers and musicians to stage what would have been a 50-show run. According to A&E network, Jackson felt tired but optimistic after rehearsals, often telling his team he needed to “pace himself.”

Final rehearsal at Staples Center

On the evening of June 24, Jackson performed at a full rehearsal that lasted until around midnight (Wikipedia (the online encyclopedia)). He returned to his rented home at 100 North Carolwood Drive in Holmby Hills at about 12:05 a.m. on June 25. From there, the night unraveled.

Where was Michael Jackson found after he died?

Jackson was discovered unresponsive in his bedroom at his rented Holmby Hills mansion. The address, 100 North Carolwood Drive, became the epicenter of the legal investigation.

Paramedics were called at 12:21 p.m. after a security guard placed the 911 call—about 82 minutes after Jackson was found unresponsive, according to later reporting (A&E network). When they arrived at 12:26 p.m., they found Jackson lying in bed, not breathing, and without a pulse (Wikipedia (the online encyclopedia)).

Discovery by paramedics

Paramedic Eddie Wayne testified that Jackson’s body was still warm, suggesting he had not been dead long (Wikipedia (the online encyclopedia)). They attempted CPR and rushed him to Ronald Reagan UCLA Medical Center, where he was pronounced dead at 2:26 p.m.

The implication: Jackson likely died alone, with only Murray present, during a window of time when the physician was occupied with phone calls.

Did Michael Jackson live in Ireland?

After the 2005 child molestation trial, Jackson spent a period outside the United States, including time in Ireland in 2006–2007.

Rental in Grouse Lodge, County Westmeath

Jackson rented the Grouse Lodge recording studio in County Westmeath, where he stayed intermittently with his children (Wikipedia (the online encyclopedia)). He used the facility to record music and reportedly enjoyed the privacy the rural Irish setting offered.

2006-2007 period

During that time, Jackson worked on material that would later appear on posthumous releases. He was also photographed in Dublin on several occasions, bringing a sense of normalcy to his children’s lives away from the media glare.

The catch: While Jackson’s Irish sojourn provided him temporary relief, it did not solve the underlying sleep issues that would ultimately lead to his dependence on propofol.

How many plastic surgeries did Michael Jackson have?

Jackson’s changing appearance over decades fueled endless speculation. While the exact number is unverified, multiple sources indicate he underwent at least two rhinoplasties and several other facial procedures (Wikipedia (the online encyclopedia)).

Nose jobs and other procedures

His first rhinoplasty reportedly occurred in 1979 after a fall during dance rehearsals. Subsequent surgeries altered his nose, chin, and cheeks. Jackson also used skin-lightening treatments for vitiligo, a medical condition, which was often mistaken for cosmetic surgery.

Changes in appearance over time

By the 2000s, his nose had become noticeably narrower, and his jawline more defined. The total count of surgeries is estimated at 12 or more, though Jackson never publicly confirmed a final number.

The pattern: The speculation about his surgeries obscured the reality of his vitiligo, a condition he never fully acknowledged in public.

How much did Pepsi pay Michael Jackson for burning his hair?

The 1984 Pepsi commercial accident remains one of the most infamous moments in Jackson’s career. During the filming of a commercial at the Shrine Auditorium in Los Angeles, a pyrotechnic malfunction ignited Jackson’s hair, causing second- and third-degree burns on his scalp (Wikipedia (the online encyclopedia)).

1984 Pepsi commercial incident

Jackson was performing a song for the commercial when the explosion occurred. He was rushed to the hospital and underwent treatment for burns. The accident led to Jackson’s addiction to painkillers, which later contributed to his medical reliance on doctors like Dr. Murray.

Legal settlement amount

PepsiCo settled out of court with Jackson, reportedly paying him $1.5 million (Biography.com). Jackson donated the entire settlement to the Brotman Medical Center burn unit.

“I was in a lot of pain, but I didn’t want to let the fans down. I went back to work even though I was hurting.”

• June 25, 5:00 a.m. — Second dose of midazolam.
• June 25, 7:30 a.m. — Third dose of midazolam.
• June 25, 10:40 a.m. — Murray administers 25 mg propofol.
• June 25, 11:18 a.m. – 12:05 p.m. — Murray makes phone calls lasting about 47 minutes.

Quotes from the trial and investigation

“I didn’t know that propofol was being used outside of an operating room. I thought it was an anesthetic that should only be used by an anesthesiologist.”

— Eddie Wayne, paramedic, testifying about his discovery

“Mr. Jackson was a human being. I made a mistake. I will carry that with me for the rest of my life.”

— Dr. Conrad Murray, in his 2011 court testimony

“Propofol intoxication, with benzodiazepine effect, is the cause of death. It is a homicide.”
