A California woman now faces hard time for a federal crime after pleading guilty to a hate-motivated attack against students at the United States’ oldest Catholic school for girls.

Last January, Sonia Tabizada pleaded not guilty to federal charges after threatening violence against students at Georgetown Visitation Preparatory School in Washington, D.C. In a voicemail message to the school, Tabizada threatened to “f**king kill your kids” unless they reversed position on their alumni magazine’s editorial decision to include same-sex marriage announcements. She even claimed that bombing the school would be “a mission from God” for which she would bear no guilt.
