IMO the bolded and underlined (by me) quote has been taken out of context. If you look at the link below, it's talking about
what aggravating factors Pennsylvania law prosecutors can cite for the death penalty.
In the case of Ms. Virzi, the DA’s office cited four: the defendant committed the killing while in the perpetration of a felony; the offense was committed by means of torture; the victim was under 12 years old; and the defendant has a significant history of felony convictions involving the use or threat of violence.
Then it goes on to say....
Although Ms. Virzi does not have a criminal history, if a jury finds her guilty of the charges against her in this case, those convictions will count as a criminal history for the purpose of sentencing.
IOW... the 1st paragraph isn't 100% of what Virzi did as stated on the paragraph above. But it appears it was by means of torture, considering what she did to his twins genitals, and the infant was definitely under 12 yrs old.
