A 19-year-old Missouri man was arrested after driving 560 miles to Winthrop Harbor twice in three days in an attempt to have sex with a 13-year-old girl, police said. Patrick R. Tullis of Independence, Mo., is charged with indecent solicitation of a minor and unlawful possession of child pornography, but additional charges are expected after a forensic investigation of his computer is complete, authorities said. The girls mother became alarmed after reading Facebook messages between her daughter and the man, who tried to lure her by posing as a guitarist in a rock band, Winthrop Harbor Detective Chris Willets said.
