Filter mask as a new candidate of personal belonging used in cadaver identification – a case report

Abstract

The case report presents an identification process based on DNA isolated from personal belongings, including a filter mask. In May 2021, an unidentified 65-year-old male corpse was revealed by the city’s outskirts road. Since it was impossible to use material from living relatives for comparative analysis, the samples of personal belongings of the alleged victim were used instead: clippings of the filtering face piece type 2 (FFP2) face mask (parts adhering to the nose and the earlobes, the central part of the mask), swabs from the razor (blade and shaft), toothbrush shaft, and toothbrush filaments clippings. The presented case indicates the need for collecting a wide range of samples for genetic analyses, including filter masks as an alternative item of personal belonging.
