Operations at the DeKalb County Courthouse are set to resume as usual on Friday, following a tense morning lockdown on Thursday. A suspicious package found inside the building triggered an evacuation and an hours-long investigation. The package, discovered in the Superior Court Clerk’s Office, prompted swift action from the DeKalb County Sheriff’s Office and courthouse marshals.

Decatur Fire responded to assess the situation, eventually determining that the envelope contained a green, gel-like substance. Officials later confirmed that the contents were non-hazardous. Investigators traced the envelope back to a prison inmate, though it remains unclear if the sender intended harm.

Authorities are now working to identify individuals who could face criminal charges. The courthouse reopened Thursday afternoon after the threat was ruled out, and officials expect no further disruptions. For now, it’s business as usual—but with heightened awareness of unusual mail deliveries.
