In the pilot of CSI there was a guy who was killed supposedly because he got rich from a slot machine and one of the guys was jealous. They thought that he had jumped off the roof or someone had pushed him. They used dummies and threw them off different ways and saw how they landed, then they matched their landing positions to the victim. Thats how they found out how he died. But we think that there are too many variables to judge it like that. For instance, wind is a factor, the clothes he was wearing, etc. So we think that they needed a more sicentific way of knowing or other proof to determine how he died.
