Expert contests Jackson drug theory

An expert in the powerful anaesthetic blamed for Michael Jackson’s death has told jurors there is no way the singer could have caused his own death by swallowing the drug.

Dr Steven Shafer was testifying on what is expected to be the final day of the prosecution’s involuntary manslaughter case against Jackson’s doctor Conrad Murray. Murray’s defence lawyers had suggested the swallowing theory might be a centrepiece of their case.
