Released under the John F. Kennedy Assassination Records Collection Act of 19927 (44 USC 2107 Hote). “DATE: 11-14-2017 fs MM 92-515 Sub II MM 876-C* MARTIN KATZ, aka ITSP | Miami File 87-17771 Bufile 87-71448 The installation in the HYMAN MARTIN case, mentioned above, consists of a 42A MATE. This MATE is currently in- operative and efforts to remove and replace this 42A MATE to date have been unsuccessful. It is felt that the security of this installation has not been jeopardized by the fact that 424 MATES in Las Vegas may have been compromised. At such time as this source is replaced, efforts will be made to in- stitute some other type of coverage. With regard to installations in the offices of BENJAMIN SIGELBAUM and ALVIN I. MALNIK, in each case a 44A MATE has been used. Consistent with full security, immediate steps have and are being taken to remove these 444A MATES since it is felt their security definitely has been jeopardized. Efforts will be made to afford another form of coverage, particularly in the case of BENJAMIN SIGELBAUM. MARTIN KATZ is a bail bondsman and close associate of top jewel thieves in the Miami area. He has an office in downtown Miami in an old building. A 42A MATE has been used. It is not known that KATZ is in any- way connected with the Las Vegas group as are SIGELBAUM and MALNIK, and for this reason the security at this time is unimpaired. It is anticipated, however, that this coverage will be removed in the not too distant future as the building wherein KATZ's office is located is scheduled for demolition. ; -2- SA ~ yee ' Docld: 32288864 Page 3
