Forensic Analysis of the Letter

An Interview with Joseph A. DiZinno
Choose the audio format below that best suits your computer system.

Joseph A. DiZinno My name is Joseph A. DiZinno of the FBI Laboratory in Washington, D.C.

Since the Leahy letter arrived at USAMRIID, it was examined by personnel from USAMRIID, and the letter was decontaminated to render it safe for subsequent forensic analysis in the FBI Laboratory. The letter was then transported by an FBI Agent from USAMRIID to the FBI Laboratory and immediately forensic analysis begun.

The type of evidence that we attempt to recover from the letter are following our standard protocols: any evidence that would subsequently possibly identify a suspect in this case.
