Dr. Alon Steinberg took the stand Wednesday, explaining to the jury both the overall role of a cardiologist, and also the ways in which Murray's practices deviated from general medicinal standards.

Steinberg, who said he was not an anesthesiologist and had reviewed Murray's case only via transcripts so that he could judge the Dr. in his own words, testified that he found 6 cases in which the doctor deviated from the standard of care, and each amounted to gross negligence, TMZ reports

One of the deviations involved the administration of CPR, which Steinberg said should have been given to Jackson on the floor, not the bed, as was the case. 

The witness, one of three who are expected to conclude the prosecution's case against Murray, also made the note that the drug Propofol should never be used for sleep, only hospital procedures.
