Some letters/parcels may carry actual threat in the shape of an Improvised Explosive Device or other dangerous/hazardous substance, including poisons. Most of such abnormal communications are either anonymous or pseudonymous. A S Osborn in his monumental book Questioned Documents (1929) wrote an exclusive chapter on “Anonymous Letters” in which he mentioned “the anonymous letter writer has appropriately been called an assassin of character and these strange missives are often properly described as poison pen letters”. The chapter describes various analytical methodsbased on language, phraseology and handwriting characteristics for the identification of the anonymous letter writer. However, this paperemphasizes the various forensic aspects of detectionas well as handling of suspicious communicationsso that the inconspicuous identifying traces of the originator remainintact and facilitate the investigation.- Reproduced Postal marks, Indentation, Obliterations, Header information, X-BIS, CBRN, TTI 18989 The Indian Police Journal FORENSIC SCIENCES - INDIA AR 0 0 ddc 0 0 388374 IIPA IIPA 2020-10-28 67(1), Jan-Mar, 2020: p.73-79 AR123379 2020-10-28 AR
