Los Angeles - A nurse who treated Michael Jackson has testified the singer asked her to help him get the powerful anaesthetic propofol.
Cherilyn Lee told jurors on Tuesday that Jackson complained he could not sleep and asked her for the drug two months before he died in 2009.
Lee was called to testify by defence attorneys for Conrad Murray, who has pleaded not guilty to involuntary manslaughter. Authorities say the doctor provided the singer with the fatal dose of the drug.
Lee says Jackson told her he had received propofol during surgery and that it was the only drug that would help him sleep.
Lee says she spoke with a doctor and told the singer the anaesthetic was unsafe to use in his home.
