It's now been one month since the disappearance of Elizabeth Thomas and state investigators say they aren't giving up hope of bringing her home.
Thomas, a 15-year-old from Middle Tennessee, was last seen on March 13. Authorities believe she is with her former teacher, 50-year-old Tad Cummins.
The last confirmed sighting of the pair was two days after their disappearance at an Oklahoma City Wal-Mart.
Authorities issued an Amber Alert for Thomas and have warrants charging Cummins with aggravated kidnapping and sexual contact with a minor.
On Thursday, TBI shared on Twitter that they "aren't giving up hope and will continue to do anything and everything to #BringElizabethHome."
District Attorney Brent Cooper wants pharmacy employees to be on the lookout for Cummins. The prosecutor said that Cummins takes blood pressure medicine and will likely need a refill.
Cooper also said Cummins left a note for his wife before disappearing, but officials think it was a diversion to mislead the investigation.
