| | Abstract | The purpose of my project is to determine the origin of blood spatters. As |
| | we all know crimes happen all the time. The mystery to every crime is who |
| | did it and what really happened. It is very rare that the crime scene |
| | investigators, or forensic scientist, are at the scene. Therefore, in this |
| | project I will play the role of an impartial scientist. To figure out what really |
| | happened, I will be Investigating blood spatter to deliver the facts using |
| | mathematical models. |
| | |
| | The procedures involve spraying synthetic blood from a spray bottle using |
| | the droplet setting from a pre-determined height. After the synthetic blood |
| | has dried, measurements will be taken of the length and width of several |
| | droplets. These measurements will allow me to determine the angle of |
| | impact. I will then draw lines through the center of these droplets to see |
| | where they meet, called the area of convergence. Measuring the back of |
| | the stain to the area of convergence, allows me to find the origin of the |
| | blood spatter, which should be above the area of convergence. Multiple |
| | methods involving mathematical principles will be used to get the most |
| | accurate data possible. |
