Teacher who reportedly ran away with student left behind a note, will need medication soon

Pharmacists are on alert for a 50-year-old Tennessee teacher who allegedly kidnapped his 15-year-old student.

According to the local district attorney, he has been on the run for nearly one month -- so he will likely need a refill of his blood pressure medication very soon.

Tad Cummins and Elizabeth Thomas have been missing since Cummins allegedly kidnapped the teen on March 13.

They were reportedly spotted together at a Wal-Mart in Oklahoma two days after they disappeared, but there have been no other credible sightings since then.

Brent Cooper, the district attorney for Maury County, Tennessee, told ABC News that Cummins needs medication to maintain his blood pressure and will soon need a refill, so pharmacists should be on the lookout soon.

Cooper also said that Cummins left a note for his wife the morning that he vanished. He did not provide details about the note, but said it appeared to be a diversion to distract investigators.

A lawyer for Cummin's wife, Jill Cummins, said she filed for divorce.
