La Toya Jackson tells Barbara Walters 'Something Went Wrong'

La Toya Jackson continues to speak out about her brother Michael Jackson's death, saying in no uncertain terms that it was "murder" in a preview of her 20/20 interview with Barbara Walters.

Appearing on "Good Morning America," Barbara shared clips from tonight's "20/20"in which La Toya talks about the ongoing death investigation.

When asked if she believes Dr. Conrad Murray killed Michael, La Toya says sternly, "Barbara, something went wrong." La Toya said she also believes Michael was dead for some time before 911 was called.

Additionally, she makes a shocking claim that Michael's son Prince was called in to help resuscitate the fallen pop star when the doctor found him unresponsive. "Why would you want to do that that to a child," she asks, "especially when you knew that Michael was no longer alive?" La Toya says she believes the reason behind this was for Murray "to show [he] had nothing to do with this."

At Michael's funeral, La Toya says he looked "absolutely fabulous," dressed in white pearl beads and a big gold belt, "like a belt that you win being a boxer."

"His hair was done beautifully," she added. "His makeup was done beautifully."

The full interview airs tonight on ABC's "20/20."
