In the realm of crime-solving, DNA analysis has emerged as a groundbreaking tool. In a recent example, DNA obtained from chewing gum led to the arrest and conviction in a cold murder case from the 1980s.
DNA analysis, or deoxyribonucleic acid analysis, has revolutionized the forensic field. It has become the gold standard for identifying suspects and convicting criminals.

Back in the 1980s, a brutal murder gripped a small town in Oregon. Despite extensive investigations, the case went cold for decades.
Fast forward to the present, a team of dedicated detectives decided to reopen the case. They began with re-examining all the evidence from the crime scene.
Among the preserved evidence, a piece of chewing gum caught the investigators’ attention. The gum, discarded at the crime scene, was sent for DNA analysis.
The DNA extraction process involved several steps:
- Cell disruption: Breaking down the cell walls to release the DNA.
- DNA purification: Removing unwanted cellular debris.
- DNA isolation: Separating the DNA from other cell components.
The DNA sample extracted from the chewing gum was then compared to DNA profiles in the criminal database.
The result? A match.
With a solid DNA match, the detectives finally had a lead. They arrested the suspect, who had been living a quiet life, oblivious of the storm that was about to hit him.
The court case was quick. The prosecution’s compelling evidence, centered around the DNA found on the chewing gum, led to a swift conviction.
The victim’s family finally got the closure they had been longing for. Their relentless pursuit of justice had paid off.
