The trial of Dr. Conrad Murray, who was Michael Jackson's personal physician and is facing charges of involuntary manslaughter in the matter of the singer's death, is into its second day.

The prosecution's case is believed to be structured to suggest that Murray administered the drug Propofol illegally and abandoned basic principles of medical care. The defense, meanwhile, hopes to suggest that Jackson managed to ingest the fatal dose on his own, after Murray left the room.

The prosecution's witnesses on the second day of the trial testified that Murray insisted the singer was in perfect health in the days before he died, the New York Times reported.

Kathy Jorrie, a lawyer hired by entertainment group, AEG, testified that Murray requested a CPR machine at the venue of Jackson's concerts. However, when questioned on the need for the piece of equipment, Jorrie said that Murray dismissed it as a precaution.

“Murray told me repeatedly that Jackson was in perfect health,” Jorrie testified on Wednesday, in the Los Angeles County Superior Court.

In addition, Paul Gongaware, also from AEG, re-took the stands Wednesday. Paul testified that Jackson had a little bit of a slower speech pattern, just a slight slur in speech, after visits to Dr. Arnold Klein, who Jackson was supposedly consulting for alleged skin problems. 

The trial began Tuesday with a shocking photograph of the singer's body and a recording of his allegedly slurry voice, on an audio tape.
