Sometimes police find traces of blood at the scene of a crime but they dont know who it come from. How can they even begin to find out? The best way to ascertain whose blood it is, is to compare it with a sample taken from the victim or the suspect.
There are times when police believe that they know who the blood belongs to, but they cannot find that person and therefore cannot do a blood match.
An investigation is more difficult if the police suspect that the blood came from a victim or perpetrator whose whereabouts is unknown. Today, science can assist. DNA taken from the blood left at the scene can be compared with DNA taken compulosrily from the genetic parents of the person they believe the blood belongs to. If it is their offspring, the DNA samples will be almost identical.
Do you think police should be able to take blood from the parents of suspects?
