Remember when Michael Jackson's physician, Dr. Conrad Murray, said he didn't kill the pop-star but everyone else said that he did. Well guess who was right? (It was you, pat yourself on the back).

Michael Jackson’s personal physician will be charged with manslaughter within the next two weeks, a law enforcement source told FOXNews.com.

The source initially said Dr. Conrad Murray could be arrested as soon as next Wednesday — but investigators have decided to execute one more search warrant, likely at a Los Angeles pharmacy, next week in an attempt to gather more evidence against him. The arrest is now expected the following week.

Murray isn’t the only doctor who faces criminal charges in connection with Jackson's death on June 25. A law enforcement source told FOXNews.com that Jackson’s longtime dermatologist, Dr. Arnold Klein, will be hit with charges related to medical malpractice. Investigators are still building their case against Klein, and he will not be arrested for at least another two weeks, the source said.

Jane Robison, spokeswoman for the Los Angeles County District Attorney's office, denied that prosecutors had decided to charge Jackson's physicians. “Until police complete their investigation and bring it to our office, there is no way to know what charges may be filed and against whom,” she said.

But the source told FOXNews.com that the DA's office is currently in talks with investigators about whether they will offer Murray the option of surrendering in Los Angeles, or if he will be arrested in Houston, where he is currently staying.

Investigators initially had hoped to charge Murray with a more serious crime than manslaughter — a defendant may be charged with second degree murder in California without the presence of a motive — but prosecutors are concerned that a jury will be unlikely to convict without one, sources said. Unless a "smoking gun" is found in next week’s search, Murray will be charged with manslaughter.

Law enforcement sources previously told FOXNews.com that Murray admitted he gave the King of Pop the intravenous anesthetic propofol to help him sleep just hours before his death — and that propofol was at least a contributing factor in the 50-year-old entertainer's death.

I don't know, that sounds like a weak argument to find someone guilty of manslaughter. I mean, I give my roommate a bottle of gin and sleeping pills each night and tell him it's magic night-night medicine, but I don't think I should be charged with murder if the dude takes to many and overdoses. Oh, did I mention my roommate is a three-year-old child, is that important?
