Michael Jackson was known the world over for his music and entertainment legacy — he wasn’t named the “King of Pop” for nothing. His long career full of hit songs, show-stopping performances and celebrity collaborations has made him a household name. Although his life wasn’t without controversy, there was no denying that Jackson left an indelible mark on music history.

Guinness World Records awarded Jackson multiple awards, such as the outstanding title of “most successful entertainer of all time,” a designation based on the recording artist’s more than 1 billion worldwide record sales. If you’ve been living under a rock — or are simply part of a different generation — Jackson’s career skyrocketed into the stratosphere of pop music with his 1982 album “Thriller,” his sixth solo release. All of the singles from the album, which includes “The Girl Is Mine,” “Billie Jean,” “Beat It,” “Wanna Be Startin’ Somethin’ ,” “Human Nature,” “P.Y.T. (Pretty Young Thing),” and “Thriller,” made it onto the Billboard Hot 100 chart’s top ten list. He remains the best-selling album of all time, having sold 70 million copies worldwide. As one might imagine, such a momentous album completely changed the music industry forever, which is why Jackson remains one of pop music’s most important figures.

Unfortunately, Jackson’s career was cut short on June 25, 2009, when the pop star had a heart attack and passed away. Unbeknownst to many, he suffered a lot before succumbing to his tragic death – which showed up on his autopsy result that was made by a doctor who eventually went to prison after losing a case of wrongful death lawsuit. Read on to learn more about Jackson and what was discovered on his autopsy.

In 1984, Jackson got into a gruesome accident that Entertainment Weekly described as an “accident so surreal it could happen only to him.”

On a fateful night of Jan. 27, 1984, Jackson was dancing down a staircase at Los Angeles’ Shrine Auditorium for a commercial ad shoot for Pepsi when a smoke bomb exploded two feet away from his pomaded curls. Jackson’s curls went into a fiery blaze, and he fell to the floor, wailing in pain, screaming for his brother Tito Jackson.

With the shocking commotion unfolding, people were screaming, claiming that he had been “shot” and was “dead,” but the fire was put out, and he was safe.

However, the aftermath of the incident left Jackson wounded badly as he suffered second and third-degree burns on his scalp and was wheeled from the venue in bandages, but the celebrity that he was remained. Knowing that the media was around, he instructed the emergency team to leave his iconic glove on to keep the pizzazz down.

As he recovered from the burns, he discovered the existence of a hyperbaric oxygen chamber, which he attempted to buy so that he could sleep in so that it could help him heal faster.

Jackson threatened to sue Pepsi, but he withdrew when they paid him $1.5 million on top of his $700,000 fee. Sadly, this was not the only tragic thing that happened to Jackson in his lifetime.

On June 25, 2009, paramedics rushed to Jackson’s house in Bel-Air, Los Angeles, California, after a distressing 911 call from his physician.

According to the medical autopsy that The Los Angeles Times had obtained, the emergency response team rushed to the Jackson residence after Dr. Conrad Murray, Jackson’s primary care physician, called 911 because Jackson entered into cardiac arrest. However, despite extreme efforts to save his life, Jackson died in the hospital.

Upon examination of the autopsy, it was revealed that Jackson’s head hair was “sparse” and only connected to a wig, a possible aftermath of his 1984 hair burn. Notably, the coroner noted that he has “patches of light and dark pigmented areas” and there was a “dark black discoloration” on his upper forehead near his hairline. He also had discoloration on his eyebrows, eyelashes and lips, and gauze was found on his nose. An ETT tube was placed in his mouth. There was also red discoloration on his chest, and a catheter was also present. Suspiciously, there were also puncture wounds present on his shoulder, arms, and ankles, as well as a bruise on his left inner leg and knees.

As Jackson’s death was reported, the singer’s health care sparked curiosity and investigation. Jackson’s mother Katherine, along with the singer’s children, sued AEG Live for his death because of the negligent hiring, retention, and supervision of Murray.

CNN reported that an expert witness was called during a court hearing at the time and they testified that Murray was not the “appropriate physician” for Jackson because he was a cardiologist and not trained to treat the singer’s special needs, which included substance abuse and difficulty sleeping.

Dr. Christopher Rogers, the forensic scientist who investigated Jackson’s body, discovered that a propofol overdose had killed Jackson, and several sedatives Murray gave him that morning contributed to his death.

In 2011, Murray was convicted of involuntary manslaughter and had his medical license revoked.
