Emails written by Stacey Howe were seized by police in a criminal investigation into the singer's death.
Two messages sent from Ms Howe's email account are now being examined by detectives trying to find out why Jackson was prescribed lethal doses of prescription drugs.
The latest development comes amid reports that documents at a storage centre and a lock-up owned by Dr Murray were destroyed as Jackson lay dying - with suggestions of a possible cover-up.
Police also revealed that Dr Murray, who could face manslaughter charges, confessed to keeping a secret drugs cupboard at Jackson's mansion.
A search warrant filed with the Los Angeles courts on Thursday formally names Dr Murray as the key suspect in a manslaughter investigation into Jacko's death.
The men in charge of Michael Jackson's estate have recovered a missing £3million - secretly hoarded by the star's financial adviser. Dr Tohme Tohme handed over the money to lawyers administering the late star's estate this week. But he insisted the singer always knew he had the cash. The Lebanese doctor claimed Jackson gave him the money to buy a house in Las Vegas.
