An AJC investigation: At a Georgia prison notorious for drug smuggling, 23 cases in four years were dismissed because the suspected drugs never made it to the state crime lab

From the Atlanta Journal Constitution News:

In 2020, the Georgia Department of Corrections announced that two of its officers had been arrested after they allegedly tried to smuggle methamphetamine and tobacco into Calhoun State Prison in Hot Pockets packages, according to a GDC news release at the time. The cases were later dismissed because the agency failed to submit the evidence for testing, according to District Attorney Joe Mulholland’s office.
