It bugs the hell out of me why this has not been solved.
DNA technology has revolutionised crime fighting. Its power lies in its ability to irrefutably link criminals to their crimes, bringing justice to victims and closure to cold cases.
As technology advances, we’re seeing an increasing number of once-unsolvable cases being cracked wide open, thanks to the humble DNA molecule.
Despite the misconception that DNA technology can go no further, it’s actually just getting started!
In the mid-1980s, British geneticist Sir Alec Jeffreys developed DNA fingerprinting, a technique that analyses specific regions of the genome to produce a unique identifier.
It was a game-changer. It meant that a burglar – or worse – could be definitively linked to a crime scene by leaving behind something as insignificant as a hair follicle.
Just as each person has unique fingerprints, so too does each person have a unique DNA profile.
One of the most famous cases to benefit from advances in DNA technology is the Golden State Killer.
For over 40 years, the man behind a terrifying crime spree in California that included 13 murders and more than 50 sexual assaults, remained a mystery.
That was until 2018 when DNA technology identified Joseph James DeAngelo as the perpetrator.
Investigators used a novel approach, uploading a DNA profile from one of the crime scenes to a genealogy website. DeAngelo was eventually identified through his family’s DNA profiles.
Familial DNA searching, as used in the Golden State Killer case, involves searching DNA databases for profiles that partially match the DNA from a crime scene.
This technique can identify close relatives of the perpetrator, providing a new avenue of investigation.
Familial DNA searching has raised privacy concerns, but its potential to solve cold cases cannot be understated.
Next-Generation Sequencing (NGS) is the latest advancement in DNA technology.
It provides even more detailed information from DNA, including predicting a person’s physical appearance and ancestral origins.
As the technology becomes more refined and accessible, its potential in crime-solving is enormous.
In the race against time, rapid DNA analysis is emerging as a potent tool. Traditional DNA analysis could take weeks, even months, but rapid DNA systems have cut this down to mere hours.
This expedited process allows law enforcement agencies to quickly establish a suspect’s involvement in a crime, leading to swift justice and potentially preventing further criminal activities.
DNA databases, which store DNA profiles of convicted criminals and arrestees, play a crucial role in the fight against crime.
However, their existence raises substantial ethical and privacy concerns.
Balancing the potential benefits of these databases in solving crimes against the right to privacy remains a complex issue that requires ongoing discussion and regulation.
The public’s role in solving crimes via DNA technology is noteworthy.
Increasingly, people are utilising direct-to-consumer genetic testing services, and some are voluntarily uploading their genetic data to public databases.
This trend was crucial in solving the Golden State Killer case and could potentially help solve numerous other cold cases.
The role of DNA technology and its impact on modern crime-solving is profound. It serves as a silent hero, unearthing truth from the shadows and bringing justice to light.
Despite ethical concerns that need careful handling, the potential of DNA technology in criminal justice remains enormous and untapped.
As it evolves, we can look forward to a future where no crime is left unsolved, and justice is always served. Unless Minority Report becomes a reality then DNA technology is out the window!

It bugs the hell out of me why this has not been solved.
I feel like there should be more killers who use the internet especially in today's world.
Thanks for this. Anymore podcast lists coming anytime soon??
