 Brent Cooper, the district attorney for Maury County, Tennessee, told ABC News on Tuesday that Cummins is on medication to control his blood pressure and should need a refill, so pharmacists should be mindful of customers who look like Cummins or Thomas. “We knew he was probably due for a refill and there was a good chance he would refill that or try to.
– It has been a month since Tennessee teacher Tad Cummins disappeared with 15-year-old student Elizabeth Thomas—long enough for the 50-year-old to need a refill of the medication he takes to control his blood pressure. Maury County District Attorney Brent Cooper has asked pharmacists to watch out for customers who look like Cummins or Thomas in case they surface to refill his prescription, reports ABC News. "We knew he was probably due for a refill and there was a good chance he would refill that or try to," the DA says. "If they are in Mexico, he could probably buy them without a prescription." Cummins is wanted on charges including kidnapping and sexual contact with a minor. Cooper tells WKRN that Cummins left a note for his wife the day he disappeared with the teen, saying he had a job interview and would be back later. The teacher, whose wife has filed for divorce, was apparently trying to buy himself time and throw investigators off the trail, the DA says. Cooper, who says he is willing to jeopardize the criminal case if it means getting Thomas home safely, has urged the teen to at least borrow somebody's phone and reassure people that she is OK, Fox 17 reports. "At some point, we're going to find them through good police work or a lucky break," the DA says. "We'll take either one." The only confirmed sighting of the two was at an Oklahoma City Walmart two days after they disappeared.
