LOS ANGELES – Michael Jackson’s struggle against drug addiction was put on display Monday during opening statements of his mother’s wrongful death case against concert giant AEG Live.

Competing portraits of Jackson emerged during the first hours of the trial, with Katherine Jackson’s attorney acknowledging the pop star’s drug problems while also trying to show he was a caring son and father.

AEG attorney Marvin S. Putnam, however, said the singer’s guarded private life meant the company was unaware that he was using the powerful anesthetic propofol.

“The truth is, Michael Jackson fooled everyone,” Putnam said. “He made sure that no one, nobody, knew his deepest, darkest secrets.”

A jury of six men and six women will determine whether AEG should pay Jackson’s mother and three children after his 2009 death from an overdose of propofol.

Millions and possibly billions of dollars in damages are at stake in the case that opened with private photos and video clips of Jackson dancing.

Katherine Jackson’s attorney Brian Panish also played a song that Jackson wrote for his three children, and a note the singer had written for his mother that brought tears to her eyes as she sat in court.

Katherine Jackson sued AEG Live in September 2010, claiming it failed to properly investigate physician Conrad Murray before allowing him to serve as Jackson’s doctor as he prepared for his “This Is It” shows.

Katherine Jackson is also suing on behalf of her son’s three children — Prince, Paris and Blanket.

AEG denies it hired Murray, and its attorneys have said they could not have foreseen the circumstances that led to Jackson’s death at age 50.

Panish told jurors that AEG executives ignored warning signs about Jackson’s health and were motivated to push the singer and his doctor to improve their own financial fortunes.

“We’re not looking for any sympathy,” Panish said. “We’re looking for truth and justice.”

With Jackson’s mother, brother Randy and sister Rebbie seated in the front row of the courtroom, jurors were shown numerous slides and several scribbled notes.

A couple of jurors nodded when the lawyer referenced Jackson’s achievements, including successful concert tours and a Super Bowl performance.

Katherine Jackson dabbed her eyes after Panish read a note that her son had written to her, in which he detailed his feelings about her.

“All my success has been based on the fact that I wanted to make my mother proud,” the singer’s note to his mother said, “to win her smile of approval.”

The personal touches came after Panish spent the first half of his presentation detailing Jackson’s struggles with prescription drug abuse throughout the last half of his life.

He also showed jurors numerous emails sent between AEG executives concerning Jackson’s health and their concerns that he wouldn’t be able to perform 50 planned concerts in London.

Putnam recounted the chaotic days following Jackson’s death as investigators and the public tried to figure out how the singer died unexpectedly. He urged jurors to remember that propofol killed Jackson.

“One thing became very, very clear,” Putnam said. “While the world may not have heard of propofol, Mr. Jackson certainly had. The evidence is going to show you that he had been using that drug for years and years.”

Putnam told jurors that AEG executives were in the dark about Jackson’s propofol use.

“How could they have known?” the lawyer asked.
