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.

Orlando Martinez, the lead detective in the case and many others tell us the true story of Michael’s death … and what our investigation found is shocking.
