The authorities are preparing to conclude their investigation into Michael Jackson's untimely death and charge his personal doctor, Conrad Murray, with manslaughter, Fox News reports. Investigators are preparing their case against Murray and are expected to carry out one more raid on a Los Angeles pharmacy before arresting him within the next two weeks. Dr. Arnold Klein, Jacko's dermatologist, is expected to face charges related to medical malpractice as well. The Los Angeles Times has reported that Murray administered a powerful anesthetic, propofol, to Jackson and then left him unattended while making phone calls. When Murray returned to Jacko's bedside, he had stopped breathing. On Tuesday, Murray released a video in which he said that "the truth will prevail." A former prosecutor blew off the video as nothing more than a "total PR stunt."
