Today, July 25, marks the four year anniversary of Michael Jackson’s death, an event that shocked the world and sparked a flurry of controversy surrounding the cause of the pop star’s sudden demise at the age of 50. In November 2011, Jackson’s doctor, Dr. Conrad Murray, was infamously convicted of involuntary manslaughter as a result of Jackson’s overdose on a lethal combination of sedatives that he prescribed.

Unsatisfied with Murray’s conviction as retribution for her son’s death, the singer’s mother has also filed a lawsuit against AEG Live, the corporation that was promoting Jackson’s “This Is It” tour at the time of his death. She believes that the company hired Murray and therefore is also responsible for Michael’s death. Last Friday, a sleep expert testified to the jury on the case that a drastic lack of proper sleep led to Jackson’s death and it could have been prevented with proper treatment.

Regardless of who or what is to blame for the unfortunate end of Michael Jackson’s life or the scandals and controversies surrounding him, the King of Pop’s untimely death set off a wave of mourning from loyal fans and a nostalgic resurgence of popularity for his greatest hits.
