Coroner Doesn't Believe Dr. Murray's Story

A doctor for the L.A. County Coroner's Office testified he doesn't believe Dr. Murray only gave Michael Jackson 25mg of Propofol.

Without saying Murray lied to cops during his interview two days after MJ died, Dr. Christopher Rogers testified if Murray were correct about the 25mg of Propofol, Jackson would have awakened after 3 to 5 minutes of sleep.

Rogers also testified he doesn't believe Jackson swallowed Propofol.  The defense laid the groundwork for this theory yesterday, because small amounts of the drug were found in Jackson's stomach.

And Rogers said he believes it's inappropriate to use Propofol for insomnia and that Murray's care was "substandard."
