The heartbreaking shootings near Tucson, Arizona has left U.S. Representative Gabrielle Giffords in critical condition, killed six people and wounded many more.

One of the deceased victims, 9-year-old Christina Green, was the second cousin of One Tree Hill star Sophia Bush.

Sophia has taken her grief to Twitter: “There are no words to explain what my cousin’s family is going through in Arizona. How can this be? Violence is never the answer. She was my 2nd cousin… Devastating.”

Christina was born on another day of national tragedy, September 11, 2001. She even once appeared in a book called 50 Faces of Hope that showed children born on 9/11 and which was sold to benefit 9/11 charities.

Christina’s mom, Roxanna Green, told The New York Times: “From the very beginning, she was an amazing child. She was very bright, very mature, off the charts. She was the brightest thing that happened that day.”

Rep. Giffords is the cousin of Gwyneth Paltrow. Gwyneth sent her love in a statement: “Although I have never had the pleasure of meeting congresswoman Giffords, my thoughts and prayers are with her and her family as well as the other victims of this horrible act of senseless violence.”
