Michael Jackson's mother was brought to tears on Tuesday (30Apr13) as private family footage featuring the King of Pop with his children one Christmas morning was shown to jurors as part of his wrongful death trial. Katherine Jackson struggled to control her emotions as the sounds of the Thriller hitmaker's song You Are My Life filled the Los Angeles court room, while a holiday video of the singer surprising his three kids with a dog aired on a TV. Her lawyer showed the home video clips to the 12-person jury on the second day of the trial in a bid to paint a fuller picture of the superstar's loving relationship with his sons Prince Michael and Blanket, and daughter Paris - a life which was cut short when he died from a prescription drug overdose in 2009. Katherine is suing concert bosses at AEG Live, the promoters behind the singer's doomed This Is It gigs, claiming they were negligent in ignoring her son's life-threatening health concerns and holding them responsible for hiring Conrad Murray, the medic who was convicted of involuntary manslaughter for administering the dose of anaesthetic propofol which killed the King of Pop. AEG executives have denied all wrongdoing and their legal representative told the court on Tuesday that the King of Pop was also the king of secrecy. Defence attorney Marvin S. Putnam told jurors, "The truth is, Michael Jackson fooled everyone. He made sure that no one - nobody - knew his deepest, darkest secrets." Paramedic Richard Senneff, one of the first people to respond to Jackson's home on the day he died, was the first witness to take the stand. He recounted the scene in the singer's bedroom and his struggle to revive him, repeating much of the same testimony he had given in Murray's involuntary manslaughter trial in 2011.
