A Chicago area teacher is apparently on the run and has fled the country after being accused of sexually assaulting a former student. Michael Vucic has taught at Gavin Middle School in Ingleside, Ill., for the last 18 years. The Lake County Sheriff`s office says a former student came forward Monday, telling her grandparents that Vucic sexually assaulted her multiple times in 2012, when she was under the age of 13. Vucic is charged with several counts of sexual assault.
