The Jackson family matriarch told jurors that she wants to find the truth about her son's death. She has spent nearly every day of this trial watching and listening to the proceedings in the front row of the courtroom.
She, along with Michael Jackson's three children, are behind the lawsuit accusing AEG Live of negligence and hiring Dr. Conrad Murray to care for the singer. Attorneys have presented evidence alleging that though anesthetic infusions by Murray caused the star's death, it was his tour promoters who failed to supervise the doctor. Throughout the proceedings, AEG has maintained that Michael Jackson hired Murray himself.
On Friday, jurors viewed precious moments recalled by Katherine Jackson -- the humble beginnings of a four-room house for a family of nine. The emotion-packed pictures and music capped 12 weeks of the plaintiff's case before the defense responds. Katherine Jackson described her heartache and the impact of her son's death on his three children.
Katherine Jackson said it's been difficult to listen to some of the testimony about her son during a 12-week trial, saying she's a private person by nature. Under questioning by her attorney, she testified how she was hurt when she heard her son being called "freaky" or "lazy." She said her son did not need to attend rehearsals because he knew the music so well.
About her son's history with pain medications, she testified he needed them for his burned scalp. But she said she made many unannounced visits to his home and never saw him under the influence. At the urging of the Jackson siblings, she agreed to join in an intervention. When they got to Michael Jackson's home, she said the singer was fine.
The final question from her attorney: "Do you miss your son?"
Her response: "Words can't explain."
Katherine Jackson was too tired to continue her testimony Friday afternoon. She will be back on the stand on Monday.
On Thursday, the court heard from an expert on propofol, the sedative Michael Jackson overdosed on back in 2009.
Jurors also heard from a financial expert who testified that Michael Jackson could have earned up to $1.5 billion if he had completed the London concert and then taken the show on the road.
The family's lawsuit seeks $40 billion in damages.
