Students in six campus residence halls across South Campus were notified last week that their mail could be at risk.
UNC’s Department of Public Safety is investigating instances of mail tampering — a federal crime involving opening, destroying or damaging someone else’s mail.
DPS spokesman Randy Young said one person of interest has been identified in an ongoing investigation into security issues in certain residence hall mailboxes. The affected residence halls include Hinton James, Ehringhaus, Craige, Morrison, Odum Village and Ram Village.
“Suspicious conditions were reported to us by (the Department of Housing and Residential Education), and it was ascertained that security was being compromised due to a manufacturer defect,” Young said.
The defect could allow individuals to access mailboxes that don’t belong to them, he said.
The communities involved have mailboxes from the same manufacturer and are made with the same materials, said Rick Bradley, assistant housing director, in an email.
He said other residence halls are not affected because they have mailboxes from different manufacturers, or the same manufacturer but made at a different time.
DPS is using security footage to investigate how widespread the tampering might be.
“There could be more than we know about right now,” he said.
