International police were searching for a 31-year-old ex-Marine this week after he took a 12-year-old British girl to France for a tryst. Toby Studabaker of Michigan, who left the military earlier this month, had been corresponding with Shevaun Pennington on the Internet. He flew to England to meet her, and the two then hopped on a flight to Paris. Studabakers sister said her brother called her to say he had not touched the girl, who claimed in her e-mails to be a 19-year-old college student. Studabaker has twice been investigated for, but never charged with, sexual misconduct with children.
