*Joe Jackson believes his son Michael’s physician, Dr. Conrad Murray, had been drinking at a strip club hours before he allegedly gave his patient a fatal dose of Propofol, reports TMZ.

Papa Joe made his accusations clear in a legal document sent to the physician on March 27, 2010 as a prerequisite to filing a wrongful death lawsuit.

Written by Joe’s attorney Brian Oxman, the document states: “On June 25, 2009, prior to treating Michael Jackson, defendant was at a ‘strip club’ called Sam’s Hofbrau in Los Angeles where he had been ‘drinking.'” The doc continues: “It was reckless for him to ‘drink’ prior to administering anesthesia to Michael Jackson. He concealed his conduct from Michael Jackson.”

The document goes on to outline Murray’s treatment and the medical emergency that ended in Michael Jackson’s death.

According to the document, Michael had “neurological, pulmonary, and anemia signs over several weeks prior to his death. In May and June, 2009, Michael Jackson was confused, easily frightened, unable to remember, obsessive, and disoriented.” Oxman continues: “He had impaired memory, loss of appetite, and absence of energy. He was cold and shivering during the summer rehearsals for his show …”

Oxman claims these problems were caused by Dr. Murray administering a “polypharmacy” of drugs to Michael. And Oxman claims, Dr. Murray “ignored the signs of Michael Jackson’s pulmonary inflammation, brain swelling, and anemia.”

Oxman alleges Murray repeatedly lied about the drugs he administered to Jackson and withheld vital information from EMTs and doctors who were trying to save Jackson’s life. He repeated all of the alleged inconsistencies that have been previously reported.

Oxman says of Dr. Murray, “His conduct was inhuman. It was an extreme violation of the standard of care.”

According to California law, Joe Jackson must wait 90 days from the date the document is delivered before filing an actual wrongful death lawsuit. The 90-day period expires Friday, the anniversary of Michael’s death.

Dr. Murray’s legal camp told TMZ, “The allegations are absolute, utter nonsense.” A rep for the defense team said Murray was not at a strip club when Oxman claims, nor was he there the night before. “In the weeks before Michael died, Murray barely had time to take a shower,” the rep stated.

As for Oxman’s allegations that Murray was drinking the night of Michael’s death, the rep says it’s not true, and that the Murray “does not drink.”

A stripper who works at Sam’s Hofbrau told TMZ she vividly remembers the night before Michael died because she’s a big MJ fan, and says, “It was dead that night. Dr. Murray definitely was not there.”

The club’s owner tells TMZ that at least twice in the last six months, a private investigator visited the venue and questioned a number of employees about Murray and if they remembered seeing him at the club.
