March 19, 1991 Honorable Abner ikva Chief Judge“or“the Use. Court of Appeals United States Courthouse Third and Constitution Avenue, N.W. Washington, D.C. 20001-2802 Dear Chief Judge Mikva: XI have recently received some inquiries regarding the letters I sent concerning mailings of incendiary materials.: This letter should provide additional details answering some of the concerns expressed. I want to assure you that appropriate prison authorities were notified of each instance where the communication originated from within a penal institution. It is important to note that the facilities involved were either state or local establishments. Internal inquiries have been initiated by prison officials of the agencies involved. No correspondence containing the devices originated from within the Federal prison system. The devices were contained in an envelope slightly { larger than a business envelope. Both the packaging and con- tents were destroyed when the devices were detonated, with the remnants forwarded to the FBI Laboratory for examination. The contents primarily consisted of match heads and a crude detonating system which would ignite the match heads when the envelope was opened. A small. fire which could injure the “person holding ‘the envelope would”*occur; however; there would'<"" ~~ be no explosion. At this time, there are no other known unique characteristics about the device or its container. crete t + ADDAGM. everett Sincerely yours, Sa 1s z ZB Q- FBO AIS—Sfoye- “os i William 8.
