Woman sentenced for killing friend's infant

Nicole Virzi, 32, was sentenced to between 35 and 80 years in prison on Wednesday in Pittsburgh, Pennsylvania. The judge imposed this term after Virzi pleaded guilty to third-degree murder and other charges. She had previously faced capital murder charges that carried the possibility of the death penalty. The agreement likely keeps her behind bars for the rest of her life.

Virzi was a doctoral student at the University of California, San Diego. She was a close friend of Savannah Roberts, the mother of the victim. In 2024, Virzi visited Roberts in Pittsburgh and helped care for Roberts' newborn twins, Leon and Ari Katz. The family had always dreamed of having twins, according to Roberts.

In June 2024, Roberts and her partner Ethan Katz took Ari to the hospital after finding injuries on his body. Virzi offered to watch Leon while the parents were away. Late that night, she called police and said Leon, who was six weeks old, had fallen from a baby hammock. Paramedics rushed the infant to a nearby children's hospital, where doctors declared him dead.

Investigators quickly determined that the severity of Leon's injuries could not result from a fall from such a low height. They arrested Virzi shortly after. The Pittsburgh police classified the death as a homicide caused by blunt force head trauma. A criminal complaint stated that Virzi also caused the injuries found on Ari, which had prompted the family to leave Leon in her care.

Virzi told investigators she always had an uncontrollable compulsion to harm children, according to prosecutors. The Allegheny County District Attorney's Office released a statement explaining the plea deal. The office said it remained committed to a trial but agreed to the offer after consulting with the family. Officials cited the best interest of the community and its protection as factors in the decision.

Roberts wrote a letter to Judge Jill E. Rangos of the Allegheny County Common Pleas Court. She said the tragedy permanently shook her confidence in humanity. Roberts described how Virzi's actions changed her as a person. She wrote that she no longer recognized the woman she used to be. Roberts noted that she never imagined her best friend could show such cruelty and violence.

Roberts described the lasting impact on her daily life. She said it took her nearly a year to use the bathroom, shower, or brush her teeth alone after learning Virzi hit Leon against the floor of their old bathroom. The impact fractured his skull. Roberts wrote that her partner Ethan had to stay outside the door and talk to her constantly. He preferred holding Ari where Roberts could see him to ensure the baby was safe. She added that she has not yet been able to leave Ari alone with a friend and is unsure if she ever will.

Local criminal defense attorney Phil DiLucente analyzed the sentence for NBC News affiliate WPXI. He said Virzi must serve the full minimum 35 years before becoming eligible for parole. DiLucente called the case strange because Virzi flew from the other side of the country to visit a friend before committing such a premeditated act. He stated it is very unlikely a parole board will allow her release. The attorney noted that the facts do not fit typical mitigating factors for parole. Virzi's attorney was not immediately available for comment.
