(Scroll down for video) A professor was arrested, charged and convicted of murder after poisoning his wife because she wanted to have another child, prosecutors in Pennsylvania said.
Robert Ferrante, who was a researcher at the University of Pittsburgh, hatched the plan to kill his wife, 41-year-old Autumn Klein, after she pressured him for a second child.
After being convicted of murder, Ferrante now faces a mandatory sentence of life imprisonment. The jury deliberated for 15 hours over two days, before finding the 66-year-old professor guilty of first-degree murder.
According to the police investigation, Ferrante gave cyanide to his wife, which caused her to die three days later. Prosecutors told the jury that Ferrante may have feared that Klein was having an affair or planning to divorce him.
Ferrante denied killing his wife, saying that he had bought the cyanide to experiment with stem cells. Police said that Ferrante bought the poison just two days before Klein became ill.
A blood test of Klein revealed that she had a lethal level of cyanide in her body.
