Jackson's sister blames doctor for Michael's death

NEW YORK — Janet Jackson blames Dr. Conrad Murray for her brother Michael's death.

She told ABC News in an interview to air Wednesday that Murray should no longer be allowed to practice medicine. "He was the one that was administering," Jackson said. "I think he is responsible."

Prosecutors in Los Angeles are weighing charges against Murray in the pop singer's death. Murray told police he administered a powerful anesthetic to the singer shortly before Jackson died June 25.

A spokeswoman for the doctor, Miranda Sevcik, said Monday he continues to maintain he neither prescribed or administered anything to Jackson that should have killed him.

Jackson told ABC's Robin Roberts that she was at her home in New York on June 25 when her assistant called to say Michael had been taken to the hospital. She told relatives to call her when they got to the hospital and grew concerned when she wasn't getting any calls back.

She says that a day doesn't go by when she doesn't think of Michael. "It just didn't ring true to me. It felt like a dream," she said. "It's still so difficult for me to believe.
