Michael Jackson died because Dr. Conrad Murray infused him with a fatal dose of propofol, at least that’s the official story … but it’s not the REAL story … and, our documentary covering it all is now available on YouTube.

A months-long TMZ investigation paints a very different picture than the official narrative … a picture of numerous doctors who are largely responsible for the King of Pop’s death.

Our documentary, “TMZ Investigates: Who REALLY Killed Michael Jackson,” hones in on one doctor in particular … the late Arnold Klein, a famous dermatologist with a practice in Beverly Hills.

Debbie Rowe, Michael’s ex-wife who worked for Klein for years, provides a shocking account of what went on in Arnold’s office between Klein and Michael.
