PITTSBURGH - A University of Pittsburgh medical researcher accused of fatally poisoning his wife plans to waive extradition at a West Virginia hearing Monday, according to a defense attorney.
Attorney William Difenderfer for Dr. Robert Ferrante, 64, said his client was on his way to turn himself in for the death of UPMC neurologist Autumn Marie Klein, 41, when he left Florida and began driving north. Klein died April 20 after suddenly falling ill.
Prosecutors said blood tests revealed a lethal level of cyanide. Ferrante had purchased more than a half-pound of cyanide two days before Klein's illness, according to prosecutors.
