The prosecutor in the Michael Jackson manslaughter preliminary hearing -- which begins tomorrow -- will not call Michael's eldest son, Prince Michael, to testify about what he saw the day his dad died ... sources tell TMZ.
Dr. Conrad Murray has said after administering CPR he ran downstairs and asked the chef to send up Prince Michael, who saw his dad's lifeless body lying in the bed.
In fact, we're told no one from MJ's family will be called to the stand during the prelim.
As TMZ first reported, prosecutors plan to call 30 witnesses during the 2-week prelim ... many of whom will be medical professionals offering opinions about the standard of care administered by Dr. Murray.
There will be no "star witness" in the prelim. Sources tell us the various witnesses will form building blocks, making the case that Dr. Murray acted recklessly by administering Propofol and other drugs to Jackson the day he died.
