Nicole Virzi, 31, is accused of killing her friend’s six-week-old newborn and seriously injuring the twin during an incident in Pittsburgh after she traveled across the country to meet the babies for the first time, according to reporting. The case centers on an alleged confession captured on video, in which prosecutors say Virzi describes hearing a “crack” around the time the injuries occurred. Virzi is charged in a manner that, if convicted, would expose her to the death penalty, the sources report. The allegations claim the newborn dies and the twin is maimed. The reporting also describes Virzi as a PhD student. The outlets do not provide further verified details in the supplied text about the medical cause of death, the nature of the injuries to the surviving twin, or Virzi’s defense position. The information presented reflects the accusations and procedural posture described by the outlets, and the case remains subject to the legal process.
