Projectiles specialized for DNA and other trace evidence collection
View Patent ↗New projectiles specialized for creating and recovering trace evidence at a crime scene are provided. A wide variety of embodiments are provided, covering several use scenarios—including, but not limited to, home security devices, which may be built into an entryway or other building structure, and law enforcement guns. In some embodiments, a projectile within a projectile is provided, which fires in the direction of a primary impact. A sampler device is provided within some projectiles, which may comprise tracing barbs, containers for analytes and even a hypodermic extraction apparatus. In some embodiments, projectiles have rebounding devices, which may overlap with aspects of the sampler device, for developing distance from a criminal suspect. Other aspects, such as GPS, fasteners and defense mechanisms, are also disclosed, which encourage recovery by the authorized user and deter interception.
1. An evidence collection system, comprising a projectile with: an extraction device configured to obtain identifying evidence and hold it wherein said extraction device is configured to obtain identifying evidence upon collision with person, animal or object; wherein said projectile is configured to be launched through a projectile guide installed within a building wall; and wherein said projectile is configured to be retracted into said wall.
2. The evidence collection system of claim 1 , wherein said system comprises a launcher configured to launch said projectile.
3. The evidence collection system of claim 2 , wherein said launcher comprises a camera.
4. The evidence collection system of claim 2 , wherein said launcher comprises a control system comprising computer hardware.
5. The evidence collection system of claim 4 , wherein said control system is configured to provide a time stamp and location associated with a launching event.
6. The evidence collection system of claim 1 , wherein said system comprises a camera.
7. The evidence collection system of claim 1 , comprising a control system comprising computer hardware.
8. The evidence collection system of claim 7 , wherein said control system is configured to provide a time stamp and location associated with a launching event.
9. The evidence collection system of claim 1 , wherein a tether is attached to said projectile.
10. The evidence collection system of claim 1 , wherein said projectile implants a tag into said person, animal or object upon said collision.
11. The evidence collection system of claim 1 , wherein said system comprises an alarm.
12. The evidence collection system of claim 1 , comprising a protective case or other armor configured to prevent access to said projectile.
13. The evidence collection system of claim 1 , wherein said projectile comprises barbs, hooks, adhesives, projections or other surface features configured for creating trace evidence upon said collision.
14. A method for deploying a projectile, comprising the following steps: launching said projectile at a person, animal or object; wherein said projectile comprises: an extraction device configured to obtain identifying evidence and hold it; wherein said extraction device is configured to obtain identifying evidence upon collision with a person, animal or object; wherein said projectile is configured to be launched through a projectile guide installed within a building wall; and wherein said projectile is configured to be retracted into said wall.
15. The method for deploying a projectile of claim 14 , wherein a system comprises a launcher configured to launch said projectile.
16. The method for deploying a projectile of claim 15 , wherein said launcher comprises a projectile guide installed within a building wall.
17. The method for deploying a projectile of claim 15 , wherein said launcher comprises a camera.
18. The method for deploying a projectile of claim 15 , wherein said system comprises a control system comprising computer hardware.
19. The method for deploying a projectile of claim 18 , wherein said control system is configured to provide a time stamp and location associated with a launching event.
20. The method for deploying a projectile of claim 14 , wherein a tether is attached to said projectile.
