MOSCOW, July 12 (RIA Novosti) - Michael Jackson's sister La Toya said her brother had been exploited as a "cash cow" by a manipulative entourage who supplied him with addictive drugs that caused his death.
"I believe Michael was murdered, I felt that from the start," she said in an interview with Britain's Daily Mail.
After Michael Jackson's death on June 25, police found a large quantity of prescription drugs in his house. According to various reports, Jackson was using powerful intravenous anesthetics to send him to sleep.
Investigators have not ruled out murder, which under Californian law includes certain types of non-premeditated killings.
"He had needle marks on his neck and on his arms and more about those will emerge in the next few weeks. I cannot discuss that any further as I may jeopardize the investigation. I can, however, say that I have not changed my mind about my feeling that Michael was murdered," his sister told the paper.
The official autopsy results are not expected for another two weeks.
La Toya Jackson also said her brother had been ready to retire from music and move on to a film directing career, but had been pressured into planning a series of 50 concerts in London.
"He was going to retire from music. 'This Is It' really was the end. He didn't want to perform any more."
She said Michael had agreed to do ten concerts, but that the promoters had forced him to agree to 50.
"It's impossible even for a healthy person to do that many shows. Michael was fragile."
She said the family will press charges against anyone they find to have been responsible for Jackson's death.
"I am going to get down to the bottom of this. I am not going to stop until I find out who is responsible. Why did they keep the family away? It's not about money. I want justice for Michael. I won't rest until I find out what - and who - killed my brother."
