From CNN:
For Ethan Katz and Savannah Roberts, the evening of June 15 was already stressful. They had gone to a Pittsburgh hospital seeking treatment for Ari, one of their six-week-old twin sons, who had a bloody and mysterious injury to his genitals.
Their longtime friend, Nicole Elizabeth Virzi, was visiting from San Diego. She was watching the other twin, Leon, in their apartment. Later that night, they received a harrowing call at the hospital from Virzi. She told them Leon had fallen out of his bassinet and struck his head on the floor. By dawn, Leon was pronounced dead at a Pittsburgh hospital. A young family was shattered. And as more details emerged about his final moments, investigators started questioning Virzi’s story.
