Yes --believe it or not the Mexican Consulate is already involved in this case ---they'll try to make sure the US taxpayers provide a comfortable jail cell (or I'm sure they'd prefer they were set free) instead of being punished under our laws. It seems we aren't giving the immigrants enough welfare money so they have to resort to this.

John Allen Rubio, 22, and Angela Camacho, 23, allegedly killed and decapitated their three children — Julissa Angela Quezada, 3, John Esthefan Rubio, 1, and 2 month-old Mary Jane Rubio — on Monday in a tiny downtown apartment.
Turvey suspects the young couple, who reportedly did not have steady income, may not have been able to handle the financial burden of three children and were desperate to alleviate their fiscal responsibility.
