The investigators have decided first to carry out a further search warrant, probably on a Los Angeles pharmacy, in an attempt to gather more evidence against Dr Murray, Fox News reported quoting law enforcement sources.
The investigators had earlier planned to charge Murray with second degree murder but decided not to push for more serious charges as they feared a jury would not convict if there was no motive, said the report.
Murray is believed to have given Jackson, propofol, a powerful anaesthetic drug used in hospitals before surgery.
The doctor might be given the choice by the Los Angeles District Attorney’s office of surrendering either in Houston, where he is currently staying, or in Los Angeles, where any trial would take place. Murray’s lawyer has said he never prescribed or administered any drug that “should have killed” Jackson, but he never specified whether he ever gave the singer propofol.
In his first public statement after the singer’s death, Murray posted a short video on YouTube on Tuesday. “I have done all I can do (to help the police). I told the truth, and I have faith the truth will prevail,” he said in the video.
