San Diego woman sentenced to 35-80 years for killing Pittsburgh twin

Nicole Virzi, a 32-year-old from San Diego, has been sentenced to 35 to 80 years in prison after pleading guilty to the 2024 murder of her best friend's 6-week-old son, Leon Katz, and the assault of his twin brother, Ari. Virzi admitted to intentionally shaking and dropping Leon, stating she had a lifelong compulsion to harm children. The plea deal spared her a potential death sentence and spared the grieving family the trauma of a trial.
Key points
- Nicole Virzi pleaded guilty to third-degree murder, aggravated assault, and two counts of endangering a child's welfare in Allegheny County, Pennsylvania.
- Virzi faces a prison sentence of 35 to 80 years, avoiding a potential death penalty that would have resulted from a first-degree murder conviction.
- The plea was reached after consultation with the victim's family, who wished to avoid the additional trauma of a trial.
- Virzi admitted to investigators that she shook Leon hard and dropped him multiple times, including on a tile floor, claiming she did not want him to die.
- The surviving twin, Ari, suffered injuries to his lower body and groin, which Virzi reported to the parents before she was left alone with Leon.
Background
This case involves a trusted family friend who visited the twins' parents in Pittsburgh in June 2024. The incident occurred after Virzi reported injuries to one twin, leading the parents to allow her to watch the other. The plea deal was finalized in October 2026, two years after the incident.
How outlets are covering it
The Los Angeles Times and Pittsburgh Post-Gazette both report the core facts of the guilty plea and sentencing. The Post-Gazette provides more detail on the victim impact statements, highlighting the family's grief and the mother's fear for the surviving twin's future. WTAE emphasizes the procedural aspect, noting that Virzi did not speak during the hearing and that her defense attorney stated no apology would be sufficient. All sources agree on the sentence length and the charges, but the Post-Gazette offers more emotional context from the family, while WTAE focuses on the legal outcome and the DA's statement.
Why it matters
The case highlights the severe consequences of child abuse and the impact of plea deals on both defendants and victims' families. It also underscores the role of trusted relationships in enabling such crimes, as Virzi was a close friend of the parents. The plea deal, while sparing the family further trauma, raises questions about justice and closure for the victim's family.
What to watch
Virzi will serve her sentence in a Pennsylvania state prison. The family of Leon Katz will continue to grieve and care for the surviving twin, Ari. The case may also prompt discussions about the use of plea deals in high-profile child abuse cases and the balance between justice and the well-being of victims' families.
