Elizabeth Thomas and her alleged abductor Tad Cummins may have fled the country to Mexico, Tennessee officials announced a press conference on Tuesday.

“[He] planned this in such a way that he had a 24-hour head start, easily enough time for him to make it to Mexico,” Maury County District Attorney Brent Cooper said.

Cummins, 50, and 15-year-old Thomas have been missing since March 13. The high school freshman is believed to be with her former health sciences teacher after Cummins alleged “groomed” Thomas for months and the two allegedly exchanged emails officials described as “romantic” in nature.

A warrant has been issued for Cummins’ arrest on charges of aggravated kidnapping and sexual contact with a minor. The latter stems from reports that the pair were caught kissing in Cummins’ classroom on Jan. 23.
