Prosecutors to seek death penalty for PhD student accused of killing friend's baby in Pennsylvania

A Ph.D. student charged with killing her friend's newborn baby and abusing the infant's twin brother while babysitting them in Pennsylvania could be sentenced to the death penalty if she is convicted, as prosecutors revealed they plan to seek capital punishment.

Nicole Virzi, 30, was charged with homicide, aggravated assault and child endangerment after allegedly abusing and killing six-week-old Leon Katz while the child's parents, Ethan Katz and his wife Savannah Roberts, took the baby's twin brother Ari to the hospital on June 16.
