While the autopsy report of Michael Jackson is still awaited, people close to him have claimed that his dependency on prescription drugs, encouraged by "enablers", led to his sudden death.

Brian Oxman, attorney and spokesman of the late singer, told 'CNN' that there were "enablers" in the star's entourage, who pressurized the singer to perform and pushed him towards prescription drugs.

"I believe (his manager) Frank DiLeo was with him at the time (of his heart attack), that is what I have been told. This family has been trying for months and months and months to take care of Michael Jackson," said Oxman.

"The people who have surrounded him have been enabling him. If you think the case of Anna Nicole Smith was an abuse, that is nothing compared to what has taken place in the life of Michael Jackson," Oxman added hinting at the role of the coterie that surrounded Jackson during his last days.

"I do not know what medications he was taking, but the reports that we have received within the family are that they were extensive. I do not know the cause of it. But it is something that I feared. This is a case of abuse of medications, unless the cause is something else," Oxman said.

The singer, who had a history of addiction to pain killers, was reportedly on a number of prescribed drugs to combat injuries suffered during his training for the comeback.

"When you warn people that this is what's going to happen and then it happens, where there's smoke there's fire," Oxman added.
