PITTSBURGH (AP) - A University of Pittsburgh medical researcher accused of poisoning his neurologist wife has been arrested in West Virginia on a criminal homicide charge.
A police complaint says Dr. Robert Ferrante laced an energy supplement with cyanide before giving it to medical school neurologist Dr. Autumn Klein hours after they exchanged text messages about how the supplement could help them conceive a child.
Allegheny County district attorney's office spokesman Mike Manko says Ferrante was arrested near Beckley, W.Va., by state police.
Defense attorney William Difenderfer has said Ferrante denies involvement in his wife's death. He hasn't responded to a request for comment on Thursday's arrest.
Police had traveled to St. Augustine, Fla., to look for Ferrante, a leading researcher on Lou Gehrig's disease.
Ferrante and Klein met at a VA hospital in Bedford, Mass.
