Overview
- David Dwayne Cassady, 57, pleaded guilty to two counts of attempted malicious use of explosive materials and received 480 months on each count to run consecutively.
 - U.S. District Judge J. Randal Hall imposed the sentence, which includes five years of supervised release with no parole in the federal system.
 - Investigators say Cassady built the devices inside a Tattnall County state prison and mailed them to the U.S. Courthouse in Anchorage and the Justice Department in Washington, D.C.
 - A plea agreement describes the bombs as functional, and officials reported that neither device detonated.
 - Defense filings cite severe anxiety and gender dysphoria, noting the defendant now uses the name Lena Noel Summerlin, while a multi-agency probe led by Postal Inspectors, the FBI, U.S. Marshals, HSI, and Georgia authorities secured the case.
