1 Body models in forensic ballistics: reconstruction of a gunshot injury to the chest by bullet fragmentation after shooting through a finger  M.J. Thali, B.P. Kneubuehl, R. Dirnhofer, U. Zollinger  Forensic Science International  Volume 123, Issue 1, Pages (November 2001) DOI: /S (01)

2 Fig. 1 X-ray of the shooter’s hand. The gunshot wound necessitated amputation of the index finger at the distal joint. Forensic Science International  , 54-57DOI: ( /S (01) )

3 Fig. 2 Unusually large entrance wound with adjacent, numerous, smaller skin perforations in which lead fragments of projectile were discovered. Forensic Science International  , 54-57DOI: ( /S (01) )

4 Fig. 3 Exit wound (projectile removed) in the victim’s back after the hollow-point projectile shed its jacket. Forensic Science International  , 54-57DOI: ( /S (01) )

5 Fig. 4 Finger model: hardwood rod (simulated bone) embedded in glycerin soap (soft-tissue substitute). Forensic Science International  , 54-57DOI: ( /S (01) )

6 Fig. 5 Experimental setup: finger model in front of the mouth of the weapon and, approximately 3ft away, a soap block (substitute chest). Forensic Science International  , 54-57DOI: ( /S (01) )

7 Fig. 6 Finger model (post gunshot) and bullet fragments found around the large entrance wound in the glycerin soap. Forensic Science International  , 54-57DOI: ( /S (01) )

8 Fig. 7 High-speed documentation: after penetrating the finger model the bullet was deformed by the separation of small fragments (copyright by Ballistics and Detonics Laboratory, Group “High-Speed Measurement Technique”, GR Thun, Switzerland). Forensic Science International  , 54-57DOI: ( /S (01) )

9 Fig. 8 Soap block with entrance wound, which corresponded in size to the real case conditions. Here, too, were numerous, small projectile fragments around the entrance wound. Forensic Science International  , 54-57DOI: ( /S (01) )

10 Fig. 9 Wound channel in the soap: entrance wound, left. The size of the model exit wound also corresponds to the real case findings. Forensic Science International  , 54-57DOI: ( /S (01) )

11 Fig. 10 The experimentally produced deformations and fragments of the projectile essentially corresponded to the projectile parts that appeared in the real case. Forensic Science International  , 54-57DOI: ( /S (01) )
