For example, they often leave footprints, hair samples, and evidence as to what kind of weapon they used to commit the crime. Earlier work had derived an equation relating the impact velocity of a liquid drop of blood to its volume and impact angle, and to the width of the dried stain it produced as determined by the known capillary and viscous behaviour of blood.
