    STATESBORO, Georgia (WJCL) — A Georgia inmate has been sentenced to 80 years in federal prison after pleading guilty to two counts of attempted malicious use of explosive materials.

David Dwayne Cassady, 57, constructed and mailed two destructive devices while incarcerated in a Georgia state prison, according to evidence presented in the case.

He was indicted in 2024.

The devices were sent to the U.S. Courthouse in Anchorage, Alaska, and the Department of Justice in Washington, D.C.

“This defendant’s devices were not only a threat to the recipients, but to every individual that unknowingly transported and delivered them,” said U.S. Attorney Bryan Stirling for the District of South Carolina. “The Department of Justice and our law enforcement partners will continue to take action against those who seek to harm the public.”

United States District Judge J. Randal Hall sentenced Cassady to 480 months on each count, to be served consecutively, followed by five years of court-ordered supervision.

Federal sentences do not allow for parole.

The case was investigated by the U.S. Postal Inspection Service, the U.S. Marshals Service, the FBI Anchorage Field Office, Homeland Security Investigations Federal Protective Service, the Georgia Bureau of Investigation, and the Georgia Department of Corrections Office of Professional Standards. Assistant U.S. Attorneys Benjamin N. Garner and Elizabeth Major prosecuted the case in the Southern District of Georgia.
