Allegheny County

Prosecution Calls Final Witness in Cyanide Poisoning Trial

The defense was expected to begin calling witnesses after a final prosecution witness in the trial of a University of Pittsburgh medical researcher charged with poisoning his neurologist wife with cyanide last year.

The last prosecution witness will be an expert who will show the Allegheny County jury an animation that's expected to explain how the poison killed 41-year-old Dr. Autumn Klein.

Her husband, 66-year-old Dr. Robert Ferrante has denied killing her - and his attorneys say they'll call medical witnesses to cast doubt on the prosecution's claim that she was even poisoned.

Among those witnesses will be the county's former coroner, Dr. Cyril Wecht a nationally known pathologist who has consulted on the deaths of JonBenet Ramsey and Elvis Presley, among others.
