Dr. Conrad Murray will make his expected appearance in a Los Angeles area courtroom Monday. According to TMZ sources, Murray is likely to plead not guilty to charges (involuntary manslaughter) that he contributed to the death of late entertainer, Michael Jackson. News of Murray pleading not guilty comes as no surprise, as the doctor has long claimed to have done nothing wrong in the hours and days leading up the Grammy winner’s death. While Murray is expected to arrive in court today voluntarily, sources say there is concern about his safety. “We’re told there is a concern about Dr. Murray’s safety because of intense feeling on the part of some Michael Jackson fans that Dr. Murray killed the singer,” reports TMZ. “We’re told the Sheriff’s Department has had its security plan in place for a while, in part because of crowd control concerns and partly because of security issues surrounding Dr. Murray.” In others news, Murray paid a visit to Michael Jackson’s final resting place at Forest Lawn Cemetery over the weekend.
