Sofia disappeared 1 day before her 5th birthday. She went missing on February 4, 2003 from Kennewick, Washington. Police believe she was abducted. Officers searched homes, questioned more than 1,000 people and chased tips from around the country and Mexico. She was featured on Tri-City Herald reports. Sofia was featured on "America's Most Wanted," and her face appeared on a NASCAR race car and on semi-trucks across the nation's highways. Sophia is a Hispanic female with long black hair and brown eyes. She was 3'0 tall and weighed 33 pounds at the time of her disappearance.
