Michael Jackson's Doctor Under Investigation: Manslaughter Charges?

Investigators are focusing on the actions of Michael Jackson's personal physician and it would appear that manslaughter charges are on the horizon.

Michael Jackson's personal doctor is the target of the manslaughter investigation into the singer's death, according to court documents filed Thursday, the day after agents seized items from the physician's Houston clinic.

A search warrant approved by a Houston judge allowed authorities to seek "property or items constituting evidence of the offense of manslaughter that tend to show that Dr. Conrad Murray committed the said criminal offense."

According to the warrant filed in Harris County District Court, authorities were looking for "items constituting evidence of the offense of manslaughter that tend to show that Dr. Conrad Murray committed the said criminal offense," the Los Angeles Times reported.

A receipt for the search warrant detailed items seized when federal drug agents and Los Angeles police descended on Murray's clinic Wednesday. Among them: 27 tablets of the weight loss drug phentermine, a tablet of the muscle relaxant clonazepam, two hard drives, notices from the IRS and a controlled substance registration.

Murray's lawyer, Edward Chernoff, referred queries to the statement he made a day earlier in which he confirmed a search warrant had been executed and that none of the items seized had previously been requested by authorities.

Los Angeles Police Department spokesman Officer Bruce Borihanh said he could confirm a search warrant was served but had no other comment.

Murray's actions and version of events seemed sketchy, and Jackson could have died as a result of a bad reaction to one or more medications that were prescribed to him.
