Pittsburgh woman sentenced for murdering infant son of her best friend
Nicole Virzi, 32, admitted in a Pittsburgh courtroom that she killed the six-week-old son of her best friend — a crime she said was driven by an uncontrollable compulsion to harm children. NBC News reports that Virzi entered a guilty plea to third-degree murder and related charges, avoiding a capital murder trial in which the death penalty had been on the table.
Judge Jill E. Rangos of Allegheny County Common Pleas Court sentenced Virzi to 35 to 80 years in prison. Under Pennsylvania law, she must serve the full 35-year minimum before becoming eligible for parole.
A trusted friend turned perpetrator
Virzi, a doctoral student at the University of California San Diego, had travelled to Pittsburgh in 2024 to visit Savannah Roberts, a close friend. Roberts had recently given birth to twin boys, Leon and Ari Katz. Virzi helped babysit the newborns during her stay.
In June 2024, Roberts and her partner Ethan Katz discovered wounds on Ari's body and rushed him to hospital. They left Leon in Virzi's care while they were away. That same night, Virzi called police and claimed Leon, then six weeks old, had fallen from a baby bouncer. He was transported to a nearby children's hospital, where he was pronounced dead.
Investigators determined that the severity of Leon's injuries was inconsistent with a fall from such a low height. Virzi was taken into custody shortly afterwards. Pittsburgh police later confirmed in a criminal complaint that Leon's death was ruled a homicide caused by "blunt force trauma to the head." It was also established that the injuries to Ari — the very wounds that had drawn the parents away from home — had been inflicted by Virzi herself.
"A compulsion she could not control"
Prosecutors said Virzi told investigators she "always had a compulsion she could not control to harm kids." The Allegheny County District Attorney's Office, in a statement explaining the plea agreement, said the decision was reached after ongoing consultation with the family and with the protection of the community in mind.
"This was a horrific case in which Virzi used her trusted relationship with the Roberts/Katz family to place herself in a situation where she could commit her horrendous acts," prosecutors said.
The DA's office had initially been prepared to take the case to trial and pursue the death penalty, but ultimately agreed to the plea and sentence in the interest of the family and community.
Mother's statement to the court
Roberts addressed Judge Rangos in a letter that described the lasting damage Virzi's actions had caused. "Nicole's actions have fundamentally changed me as a person and I feel unrecognizable from the Savannah I used to be," she wrote. "I could've never imagined that a person, let alone my best friend, was capable of the cruelty or violence Nicole displayed."
Roberts wrote that she has struggled to leave Ari out of her sight since learning the details of Leon's death. "It took nearly a year for me to use the bathroom, shower or brush my teeth by myself after learning Nicole hurled Leon to the ground on our old bathroom floor, fracturing his skull and ending his life," she wrote. She added that she has never been able to leave Ari alone with a friend and does not know if she ever will.
Roberts noted that both she and Ethan are themselves twins, and that having twins had always been a shared dream for the couple.
Parole unlikely, legal analyst says
Phil DiLucente, a criminal law attorney and legal analyst for NBC affiliate WPXI, said it is highly unlikely that any parole board would release Virzi once she becomes eligible. "It's just a bizarre case from a lot of different viewpoints that someone would fly in from across the country to see her best friend and then to do such a horrendous premeditated act," DiLucente told NBC News. "She just doesn't apply to any of the things that would be considered a mitigating factor in granting parole."
An attorney for Virzi could not immediately be reached for comment.
