Pittsburgh Mother’s Friend Pleads Guilty to Killing 6-Week-Old Twin, Faces 80 Years

Nicole Virzi, a 32-year-old woman from San Diego, pleaded guilty to third-degree murder and other charges for the death of her best friend’s 6-week-old son, Leon Katz, in Pittsburgh. The plea deal, reached on October 28, 2026, spares her a potential death sentence but results in a prison term of 35 to 80 years. Virzi admitted to intentionally shaking and dropping Leon, as well as injuring his twin brother, Ari, during a visit in June 2024. Prosecutors accepted the plea to spare the grieving family the trauma of a trial.

Background
This case involves a tragic incident in Pittsburgh, Pennsylvania, where a visitor from California abused and killed a newborn twin. The plea deal concluded a two-year legal process that had previously seen prosecutors seek the death penalty. The case highlights the severe consequences of child abuse and the legal mechanisms used to balance justice with the emotional well-being of victims' families.
How outlets are covering it
WTAE and the Pittsburgh Post-Gazette emphasize the plea deal’s role in sparing the family the trauma of a trial, citing Deputy District Attorney Emma Schoedel and DA’s office statements. The Los Angeles Times focuses on Virzi’s background as a former doctoral candidate in clinical psychology and her admission of a lifelong compulsion to hurt children. All sources agree on the core facts of the plea and sentence, but the LA Times provides more detail on Virzi’s personal history, while local Pittsburgh outlets highlight the family’s emotional statements and the specific injuries inflicted on the twins.
Why it matters
The case underscores the severe legal consequences for child abuse and the impact of plea deals on victims' families. It also highlights the role of trust and relationships in enabling such crimes, as Virzi was a close friend of the parents. The outcome may influence future cases involving child abuse and the use of plea deals to spare families further trauma.
What to watch
Virzi will serve her sentence of 35 to 80 years in state prison. The family of Leon Katz has requested privacy and is focused on healing. No further legal proceedings are expected, as the plea deal resolves the case.
