A new formula helps CSIs determine whether a victim took a blow standing up.
1// Height of the blood at the beginning of its parabolic arc, that is, when it left the body.
2// Tangent of the angle at which the first blood drop hit the ground.
3// Tangent of the angle at which the second drop hit the ground.
4// Horizontal distance the first drop traveled.
5// Horizontal distance the second drop traveled.
