Forensic science

Today we had two detectives in and they had a talk to us about what they do on crime scenes. First off they get a phone call from a witness and then they call in the front line cops or if it's a murder they call in the detectives and they do finger prints foot prints DNA test around the whole house. After they have all the information they send it to the Forensic science in wellington and after about a few days it comes back and it should have someone's names and all there details on it then they can take them to court and arrest them.
