Dr. Conrad Murray is at fault for Michael Jackson's premature passing, she says.
"He was the one that was administering," she tells ABC's Robin Roberts in an exclusive interview airing Wednesday night. "I think he is responsible."
The doc is still under investigation for the death, and has admitted to giving the icon the anesthetic propofol.
Placing blame isn't the only thing Miss Jackson is spilling in the rare sit-down.
"I couldn't believe it," she says, recalling June 25 and the moment she found out her brother was deceased.
