The Importance Of Forensic Science
Forensic science is any science used to solve unsettled crimes by providing evidences at the scene such as blood, saliva, drugs, hair and other DNA. It is important for forensic scientists to be careful in these situations otherwise, it would lead to false identification resulting an innocent person to have to pay someone else’s consequences. In 1978, Steve Barnes became a victim of improper forensic science and eyewitness misidentification in upstate New York. He was convicted of a murder and rape that he did not commit but two decades later, he was finally proved innocent after a DNA testing was obtained.
On the 18th of September 1985, Kimberly Simon’s body was found near the side of the road, raped and strangled to death. According to unclear eyewitness testimonies, Steven Barnes’ truck was seen around the crime scene while others stated otherwise. Hence, he was questioned for 12 hours straight 3 days after the crime happened but he was proved innocent. Around 2 years later, investigators used 4 different kinds of forensic science against him. First, He was asked Barnes to submit his blood, saliva and hair samples and match them with the fluid found on the victim’s underwear and other DNA’s taken from her body. They said that the result of his DNA matched the victim’s blood type but their testing was inconclusive because when the testing was conducted, it was vague. Second, His truck was examined to find an imprint of the victim’s jeans fabric on the seats of his truck.

What Causes Wrongful Convictions
488 Words | 2 PagesOne of the most accurate methods of connecting a suspect with a crime is through the use of DNA analysis. Even if no fingerprints are left behind at a robbery, for instance, a single strand of hair or skin cell from the thief can be used to positively identify a suspect. Conversely, if a suspect’s DNA does not match samples procured from a crime scene, the use of so-called “genetic fingerprinting” can exonerate, or clear, them. Concern over the issue of wrongful convictions, coupled with a sense of greater trust in DNA analysis over other, more conventional methods of prosecution, such as eyewitness testimony, has led some to call for mandatory DNA testing before any person begins serving a sentence for a serious crime, as well as
