Tiffany Rubin had all but given up hope of ever seeing her abducted child again when she received an anonymous tip through her MySpace page. Someone had spotted her 7-year-old son and ex-boyfriend in South Korea. On Easter Sunday, the Queens special education teacher caught a 15-hour flight. She sneaked into her son's school, found Kobe Lee in a classroom, disguised him with a wig and sought refuge in the American Embassy before bringing him home to Queens on Wednesday. "It's great," Rubin said. "I never thought this day would come." Her nightmare began on Aug. 21, after her ex-boyfriend Jeffrey Salko disappeared with their child after a visit.
