Ryan Hizon, 22, was recently killed in Afghanistan. A Los Angeles resident since his teens, he wasnít a U.S. citizen, nor were his parents. But under a program that allows the families of soldiers killed in action to quickly become citizens, his parents were given a final gift from their son. It's a bittersweet day for Rachel Santiago as she looks at a photograph of her son, Army Spc. Ryan Hizon, in his bedroom in Glassell Park. He was killed by an improvised explosive device Feb. 28 in Afghanistan. On this day his parents will be sworn in as U.S. citizens. A gold star hangs at the home of the family of Army Spc. Ryan Hizon in Glassell Park. After the immigration ceremony and lunch, the family drove to Forest Lawn Memorial-Park in Glendale, where they visited the grave of Ryan Hizon. His father, Rodolfo Hizon Jr., bent down to tap the grave twice. Then it was Rachel Santiago's turn. Every time Ryan Hizon would leave the house, his father would touch him.
