Forensic science has evolved over the years. In the past Forensic scientist did not have many ways to determine if a person committed a crime or not. In the early 21st century technology began to take over and it helped scientist capture the person who did the crime. In the past it would take scientist years to find out who committed crimes and today scientist are returning back to those murders and trying to figure out what happened. I know that when handling most cases that include forensic evidence scientist always look for blood, hair, fingerprints and footprints to determine who committed the murder.
