The lead lawyer for the doctor charged in connection with Michael Jackson's death has challenged a key prosecution expert about his contention that the physician was responsible for the death of the singer.
Ed Chernoff cross-examined Dr Steven Shafer, who previously testified that the only plausible explanation for the death was that Jackson had been hooked up to an IV drip of the anesthetic propofol then left alone by Dr Conrad Murray.
"That's a bold claim, isn't it," Mr Chernoff asked.
"It's an honest statement," Dr Shafer replied.
Mr Chernoff also questioned the Columbia University researcher and professor about his IV demonstration for jurors.
The defence lawyer suggested Dr Shafer had drawn conclusions that were not necessarily supported by the evidence.
Mr Chernoff said the type of IV line that Dr Shafer used in the demonstration was never found at Jackson's house.
Dr Murray has pleaded not guilty to involuntary manslaughter.
He could face up to four years behind bars and the loss of his medical licence if convicted.
Dr Shafer was expected to be the last witness called by the prosecution. After Dr Shafer's testimony ends, defence lawyers will begin presenting their case.
