Michael Jackson's doctor revealed his tragic final words before lethal overdose

Today marks 15 years since Michael Jackson's tragic death.

The 'King of Pop' had been preparing for a 50-date residency at London's O2 Arena when he suddenly passed away at his Los Angeles home on 25 June, 2009.

His personal doctor Conrad Murray told doctors that the 50-year-old had stopped breathing and appeared to have gone into cardiac arrest.

Minutes earlier, Murray had given the singer a large dose of propofol and benzodiazepine to help him sleep.

Paramedics rushed to the scene and performed CPR on Jackson, but they could not resuscitate him and two hours after Murray's 911 call, the legendary singer was pronounced dead.

Fans of Jackson were heartbroken by the news of his passing and tributes flooded in.

Dr. Conrad Murray was later charged with involuntary manslaughter following an investigation and autopsy.

During the trial, his defence argued that on the night of his death, the singer had taken eight tablets of the sedative lorazepam, but this was not administered by Murray.

"When Dr. Murray left the room, Jackson self-administered a dose of propofol that, with the lorazepam, created a perfect storm in his body that ultimately killed him," his lawyer argued.

"The whole thing is tragic, but the evidence is not that Dr. Murray did it."

Ultimately, the prosecution ruled that the 'misplaced trust in the hands of Murray cost Jackson his life.'

Murray was sentenced to four years in prison, and ended up serving less than two.

With today marking 15 year since Jackson's death, his final words have been doing the rounds online.

During his trial, Dr. Murray told the court that the last thing he'd uttered was a request for 'milk' - the name that the singer had given for the anaesthetic propofol.

The doctor told the jury during his manslaughter trial (as reported by the LA Times): "[Jackson] said, ‘Please, please, give him some milk so that I can sleep, because I know that this is all that really works for me.'

"This is just a medicine that he was familiar with, it’s called propofol.

"He said ‘Just make me sleep, doesn’t matter what time I get up.

"I agreed at that time that I would switch over to the propofol."

He said after administering the drug, he left Jackson's bedside for two minutes to use the bathroom, and when he returned he'd stopped breathing.
