Janet Jackson reveals to ABC's Robin Roberts in an exclusive interview to be aired on ABC on Wednesday night that she believes Dr Conrad Murray caused her brother, Michael Jackson, to die.

It just didn't ring true to me; it felt like a dream...It's still difficult for me to believe. It's, you know, you have to accept what it is, Janet says in the interview.

There's not a day that goes by that I don't think of him, Janet adds.
