Janet Jackson [photos] says the family did its best to put an end to Michael Jackson's addiction to prescription drugs more than once, but he rebuffed the attempts.
"Of course, that's what you do," says Jackson. "Those are the things that you do when you love someone. You can't just let them continue on that way."
"We did a few times" she tells ABC. "We weren't very successful. I wish he could answer this question for you and not me. He understood that it was out of love, out of caring. But people can be in denial."
But Janet wants to make it clear that she holds Michael's personal physician, Dr. Conrad Murray, responsible for his death.
"He was the one that was administering," adds the 43-year-old. "I think he is responsible."
She recalls the moment she found out her brother was no more: "I couldn't believe it."
"I was at my house in New York. You know, another day. Another morning. And I get a call... my assistant said, 'Your brother's been taken to the hospital. It's on CNN right now.' I called everyone. I spoke to mother. I spoke to Tito. I spoke to my nephew Austin. I spoke to my sister La Toya."
"I told them to call me when they got to the hospital. And I remember thinking 'nobody's calling me back,' so I tried calling again, and that's how I found out that he was no longer."
"It didn't ring true to me," she recalls. "It felt like a dream. It's still so difficult for me to believe. It's been a tough year."
"You have your days where it's just really, it's hard to believe. And a day doesn't go by that I don't think about him."
“I definitely won’t see the movie (Jackson's tribute film, 'This Is It') right now or maybe ever. It's too soon, too hard. It’s hard when I even see the posters for it.”
Meanwhile, even though Murray has admitted to giving the singer anesthetic propofol, which is only supposed to be used in a hospital, he is still a free man with the seemingly never ending investigation still ongoing.
