A federal grand jury has indicted Tad Cummins on two charges.
Cummins, 50, is charged with transporting a minor across state lines for the purpose of engaging in criminal sexual conduct and obstruction of justice.
Cummins is accused of leaving Columbia, TN, with his 15-year-old former student on March 13. Cummins was arrested in California on April 20.
He was returned to Middle Tennessee earlier this month and appeared for a detention hearing last Friday.
If convicted, Cummins faces 10 years to life in prison.
