- An investigation into the effect of drone flypast on textile evidence is reported.
- The surface that holds the evidence is an important factor in their retention after flypast.
- Smoother surfaces lose all evidence if the drone flyover is within 3Â m, rougher surfaces hold most evidence above 2Â m.
With increasing numbers of Police forces using drones for crime scene surveillance, the effect of the drones on trace evidence present needs evaluation. In this investigation the effect of flying a quadcopter drone at different heights over a controlled scene and taking off at different distances from the scene were measured. Yarn was placed on a range of floor surfaces and the number lost or moved from their original position was recorded.It was possible to estimate “safe” distances above and take off distance from the bath mat (2Â m and 1Â m respectively), and carpet tile (3Â m and 1Â m) which were the roughest surfaces. The maximum distances tested of 5Â m above and 2Â m from was not far enough to prevent significant disturbance with the other floor surfaces. This report illustrates the importance of considering the impact of new technologies into a forensic workflow on established forensic evidence prior to implementation.
