Michael Jackson's mother Katherine and his three children are demanding $290 million (£193.3 million) in personal damages in their long-running wrongful death lawsuit.

The King of Pop's family members have accused concert promoters at Aeg Live of negligently hiring convicted medic Conrad Murray to care for the singer as he prepared for his This Is It comeback gigs in 2009.

Closing arguments in the long-running Los Angeles trial began on Tuesday (24Sep13), when family lawyer Brian Panish revealed the exact compensation the family is demanding for the first time. His final presentation to the jury included a video documenting the Thriller hitmaker's career in an effort to show the superstar's earning potential following the doomed London residency.

He did not put a figure on Jackson's potential for future earnings, which Katherine Jackson and his three kids are also suing for, but claimed the singer was on course to have banked more than $1 billion from new music, tours and endorsements following the This Is It shows had he lived.

He told jurors, "We're not looking for sympathy. We're looking for justice. Not partial, but complete justice.

"It's about shared responsibility. Michael probably has some fault. I'm not going to deny that Michael used prescription drugs and that people told him it's risky to use propofol... (but) Aeg wanted the King of Pop in their arena in London. They would do whatever it took to get him on stage. They were so excited about how much money they were going to make. They chose to run the risk, to make a huge profit, and they lost and they're responsible."

Aeg Live bosses have denied responsibility for hiring Murray, who is currently serving time behind bars after he was convicted of involuntary manslaughter for administering the fatal dose of anaesthetic propofol which caused the superstar's death in 2009. Lawyers for the defendants are due to deliver their closing arguments on Wednesday (25Sep13).

Previous reports have placed the Jacksons' total demand for damages at more than $40 billion.
