LOS ANGELES (AP) — A dancer and choreographer who worked with Michael Jackson throughout his career testified on Wednesday that she told the director of Jackson’s ill-fated concert tour that she was worried about the singer’s health, but her plea went unanswered.

Witness Alif Sankey told a jury deciding a lawsuit that the pop star appeared thin and unprepared in 2009 for the rigors of his planned comeback concerts known as “This Is It.”
