Murray lied to a paramedic on June 25 saying that Michael Jackson was fine

Murray told paramedic Michael Jackson was fine when he arrived along with the other 911 operators at Michael's home in the morning of June 25, 2009, legal papers reveal.

Richard Senneffs, a Los Angeles paramedic who also testified at the preliminary hearing last January and tried to save Michael Jackson from an overdose of Propofol combined with benzodiazepines and other drugs, said in his statement filed in court documents.

In his testimony, Senneffs said that Murray claimed: "He doesn't have a problem. He is fine. He was practising all night. Im just treating him for dehydration."

Mr Senneff, first on the scene after a guard called 911, believed Murray lied to him about what drugs he had given Jackson.

The paramedic will be a key witness in the trial where Murray responds to the charges of involuntary manslaughter and serious medical negligence. Prosecutors believe his testimony will show Murray tried to cover his tracks after giving Jackson the anaesthetic Propofol.

When asked if Jackson was on medication, Murray replied: "No, he is not taking anything. But later, the panicking Murray confessed he had given him the anti-anxiety drug lorazepam to help him sleep.

The witness said he later saw him clearing bottles from the room.

Mr Senneff also said he found Murray performing CPR on the bed after 911 operators had told him to move Jackson to the floor.

Murray's lawyers will argue that Michael Jackson drank Propofol after Murray went out from the room to go to the restroom in the morning of June 25.

The Los Angeles Coroner ruled the case as homicide and stated in the autopsy report that the death was caused by an overdose of Propofol combined with Benzodiazepines (which contributed to the death interacting with Propofol) and other drugs. Also, the Coroner certified that was impossible for Michael Jackson drink or self-inject Propofol (another alternative hypotesis made by Murray's lawyers) and that he was in good health, without no illness that could put his life in danger.

Jury selection is set to continue on  Friday, September 23 with the face-to-face questioning of potential jurors by lawyers of both sides.

Opening statement are expected to start on September 27.

The trial, which will be televised, is expected to last about one month as Los Angeles Superior Court Judge Michael Pastor told the jury pool he expects their service will be over on or about October 28.
