The man suspected of shooting a soldier at his own welcome home party Friday in southern California has turned himself in. Ruben Ray Jurado was to be brought to San Bernardino City Police station to be booked for the attack, which authorities said left Army Spec. Christopher Sullivan in critical condition. Family members said the 22-year-old was paralyzed after gunshot wounds shattered his spine, MSNBC reported. Police said Jurado had punched Sullivan’s brother during an argument about football then shot the soldier when he intervened during the fight. Sullivan is a Purple Heart recipient, having been wounded in a suicide bombing last year in Kandahar, Afghanistan.
