ARIVACA, Ariz. AP – Prosecutors said Thursday they plan to seek the death penalty against the leader of an anti-illegal immigrant group and two others charged in an Arizona home invasion that left a 9-year-old girl and her father dead.

The trio are alleged to have dressed as law enforcement officers and forced their way into a home about 10 miles north of the Mexican border in rural Arivaca on May 30, wounding a woman and fatally shooting her husband and their daughter.
