The Murder of Steve Sparrow Recently, one night, Steve Sparrow was murdered. The custodian came in and saw someone jump out the window. Four suspects were found, Victor Vireo, Hector Hawk, Melanie Meadowlark and Wendy Warbler. The evidence found was collected and thoroughly analyzed. Eyewitness testimony, analysis of hairs and fibers, blood analysis, fingerprint analysis and DNA analysis were used to find the perpetrator. The most significant pieces of evidence tested for was Blood Type, DNA, fingerprints and hair analysis. Blood type narrowed the suspects down to 2 suspects, fingerprint and DNA narrowed it down it 1 suspect and hair analysis narrowed it down to 1 suspect also. The two suspects that seem to be very likely suspects are Hector …show more content…

DNA analysis is part of Individual evidence because it can lead back to only one person. It is circumstantial because the evidence is assumed to be part of the crime, whereas direct evidence shows that the evidence found was directly connected to the crime. It is a biological piece of evidence because it contains biological material, like DNA. To do DNA analysis, a gel made of agarose needs to be created. If there is only a little bit of DNA, PCR can be used to replicate the DNA that is found. The DNA is loaded into wells in the gel that are made when creating the gel. Since DNA is negatively charged it will repel the negative charge in the gel box, and move towards the positive end. This will separate the bands to make a pattern. Then the pattern created will be used to analyze other DNA samples to find the suspect. If every single band matches between 2 DNA well tests, that means that they came from the same person. DNA analysis could also be used in paternity cases to find out who the father/mother is. The child will have half the bands from the mother the other half from the father. Since the evidence was individual, the DNA matched only one person, Hector Hawk. This evidence is useful in the case because DNA from blood does not randomly get to the crime scene without the person being there. The blood was left behind after the victim was killed and cannot follow Locard's exchange principle because the blood is a liquid and cannot simply be traveled or exchanged by

    It can refute a claim of self-defense and put a weapon in the suspect's hand. It can change a story from an alibi to one of consent. The more officers know how to use DNA, the more powerful a tool it becomes.” This proves that DNA evidence is very reliable and is hard evidence that cannot be argued upon. DNA is either found at the scene of the crime or isn’t.

Most commonly, Forensic Scientists extract samples DNA from blood, semen or fingerprints to identify a killer, but there are more unique ways of solving a homicide. Footprints, psychology, analysis of skid marks and many more methods can be implemented to discover clues to solving a case. One that method that deems utter importance which is commonly overlooked is the study of bloodstain patterns.

    Without the help of DNA, connecting offenders to their victims and the scene of the crime, so many cases would be left unsolved. Shockingly enough, it wasn’t until 1984 where DNA was used for biological identification. Once DNA started to play such a big role in criminal justice, many cases where they didn’t have enough evidence to prosecute, were brought to court and finally solved. Even though there was such a large gap in when the offenses were first committed and when they were solved, there was still justice for the victims and their families. An important case where DNA changes everything would be that of Gary Ridgway, otherwise known as the green river killer.

    It is based on extremely sensitive PCR techniques. Using DNA evidence suspects can be linked to crime scenes from as little as the skin cells on a steering wheel or saliva on a cigarette butt. DNA based forensic methods are much more efficient than the conventional methods because of so many obvious reasons. Cases could be solved even investigations begun after decades by analyzing DNA from degraded samples. Moreover, it is possible to deduce phylogenetic/evolutionary relations through DNA based forensic methods.
