A Possible Homicide Case

In this case, we will be examining a possible homicide. The victim was found dead in the middle of the office. About 8 ft. apart there was a blood trail on the floor in between the victim and the window. It looks like the victim has suffered a head injury, and not too far away from the window lie’s a gun. There is a witness who said saw the whole thing through the window. He stated that the victim and an unknown suspect were fighting in in the middle of the room, and the suspect hit the victim with the shaft end of the gun, and then ran away. We will be determining where the victim was standing when he was attacked, and whether what the victim said was true by calculating the angle of impact and the area of origin of some the bloodstain pattern. …show more content…
First we will portion out the blood stains into different areas. We will be selecting the blood stains that are well defined from each portion and from the outer edges. Then we will measure the distances of each bloodstain to the point of convergence. We will be using the equations θ=〖(sin〗⁡〖-1〗)width/lenght to determine the angle of impact, and H=(tan)(ι)*D for the area of origin. In this specific case the bloodstains and their information were given to us. For the first blood drop given to us the width was .33mm, the length was .97mm, and the distance was 26 inches. Using the equations stated above we plug in the numbers and we determine that the angle of impact to be 19.9. After we determine the angle we plug it in the second equation and we get 9.4 for the area of origin. We will then do that for the next numbers of the remaining blood stains. The rest of the angle of impacts are 61.64, 22.2, 39.86, and the rest of the area of origin are 10.2, 10.6, and 10.0. While we look at these numbers we will then determine where the victim was standing when he was attacked, and whether what the suspect said was true. According to the numbers we can conclude that what the suspect
