  1. The morphology of gunshot entrance wounds,in connection with the dynamic creation,utilizing the ‘‘skin–skull–brain model’’ Miss Natthanita Khamchu ID 51312304

  2. The morphologic of the gunshot entrance wound The important of the morphology of a gunshot wound To obtain forensic reconstructive conclusion • Is it an entrance wound or an exit wound? • From what distance or which direction is the gun fired? • What is the type of bullet?

  3. ‘skin-skull-brain model’ • Reproducible results • Without ethical concerns

  4. ‘skin-skull-brain model’ SKIN : Silicon : Synthetic fibers

  5. ‘skin-skull-brain model’ SKULL : Polyurethane

  6. ‘skin-skull-brain model’ BRAIN : Ordnance Gelatin

  7. The gunshot • From a distance of 10 m. • From a velocity of approximately 350 m/s. • Imacon 468/Hadland-Photonics camera

  8. The dynamic creation of the entrance wound The outwardly bulging skin had appeared clearly. • The skin had no contact • with the bullet.

  9. The dynamic creation of the entrance wound The skin was more bulging and separated. The skin stretched outwardly even more in a cone shape.

  10. The dynamic creation of the entrance wound The skin moved outwardly and stretched more. The diameter of the entrance hole had increased.

  11. The morphologic of the gunshot entrance wound

  12. The morphologic of the gunshot entrance wound • Substance defect In the center of the wound, the approximate diameter depend on the bullet.

  13. The development of the entrance wound • The synthetic skin showed more elastic characteristics. Central substance defect

  14. The morphologic of the gunshot entrance wound • Ring of dirt/ Bullet wipe-off Around the substance defect, occurred when gunshot residue is rubbed on the skin.

  15. The development of the entrance wound • The synthetic skin was identical with the human skin. Bullet wipe-off/Ring of dirt

  16. The morphologic of the gunshot entrance wound • Abrasion ring/Margin abrasion Around the substance defect, created by the bullet.

  17. The development of the entrance wound • The overstretching or dilating caused the abraded skin . Abrasion ring

  18. The morphologic of the gunshot entrance wound • Contusion ring Around the entrance wound, a reddish-bluish bruising.

  19. The development of the entrance wound • The bleeding beneath the skin . Contusion ring

  20. Thank you
