Alberto Alvarez, Jackson's logistics director, apparently told investigators Murray interrupted CPR on the dying star and caused delay in calling paramedics while he tried to conceal drugs. However, Ed Chernoff, among the lawyers representing Murray, said on the legal firm's website that the statement was "inconsistent", The BBC reported.
He wrote: "This statement was given more than two months after Michael Jackson's death and is inconsistent with a statement he (Alvarez) gave the police the day after Mr Jackson was taken to the hospital. Further, his statement does not match up with much of the physical evidence found at the scene."
Chernoff added: "We would ask the public to reserve judgement until after the people's witnesses are placed under oath and subjected to the rigours of cross-examination. We are confident that a fair trial will ferret out the truth."
Murray has denied the charge, pleading not guilty to "unlawfully, and without malice, killing Michael Joseph Jackson". The doctor admitted administering Propofol to help Jackson sleep hours before his death. Jackson died aged 50 on June 25 last year at his home in Los Angeles. Coroners ruled the case as homicide mainly caused by an overdose of the anesthetic Propofol.
The next hearing has been set for April 5.
