A stage manager who worked on Michael Jackson's ill-fated This Is It concert warned an AEG executive days before the star's death that the megastar was in physical and mental decline and needed help, according to an email shown to jurors.
The message from John Hougdahl was written five days before Jackson died in June 2009. Mr Hougdahl told AEG executive Randy Phillips that he had seen Jackson deteriorate before his eyes and felt he needed help.
Jackson's mother, Katherine, is suing the entertainment giant's parent company AEG Live for negligence in the hiring of Jackson's doctor, who was later convicted of killing the pop star with an overdose of the anaesthetic propofol.
The Los Angeles trial was recessed until Tuesday when AEG executive Paul Gongaware is due to give evidence.
