LOS ANGELES (AP) – The director of Michael Jackson’s comeback tour has testified he was frightened when Jackson was shivering and seemed lost at one of his rehearsals six days before he died. Kenny Ortega told a Los Angeles jury Jackson missed several rehearsals and sometimes appeared to be under the influence of a substance. Ortega read an email he sent to the CEO of concert promoter AEG Live in which he described Jackson as a “lost boy.” Ortega’s testimony is part of a lawsuit filed by Jackson’s mother against AEG Live, claiming the company missed warning signs about Jackson’s health and did not properly screen Dr. Conrad Murray, who was convicted of involuntary manslaughter in Jackson’s death.
