How Can Blood Splatters Be Used As Evidence In A Crime?

January 22, 2009 - Science Class

I think it is very possible to use blood splatters as evidence in a crime. To use blood splatters as evidence in a crime, you could measure the blood splatter, and then use the rule y=1.2x. However, this rule will only work if the blood is dropped from a distance less than two meters. After two meters, the distance of the blood splatter is about the same, and doesn't chance too much. For example, if the blood splatter was 2 meters wide, the rule would look like: y=1.2(2). After solving, you would get y=2.4, and therefore, the blood was dropped from 2.4 meters up. Usually, the higher you drop the blood from, the wider the diameter of the blood splatter will be.I think this has something to do with the speed it picks up as it is dropping, so if you drop it from a higher place, the gravity effects it more. Sometimes the density and thickness varies depending on how far up it is dropped from.
