Deoxyribonucleic acid (DNA) has been the holy grail of evidence in courtrooms throughout the United States since it was introduced into courtrooms in 1986. 99% of the DNA strand found in any two people is identical. It is the 1% that separates and identifies each and every person. The disparity in the 1% gives each and every one of us our identity. Since DNA has been known to single out individuals like a serial number it has long been the gold standard of evidence. 

The idea that someone could manufacture a crime scene, for example, putting fake DNA on a knife sheive seems impossible. Yet, the possibility exists. Israeli scientists have discovered that by having access to a genetic database, for example, using investigative genetic genealogy from a private data base, such as in the Kohberger case, DNA can be manufactured in a DNA laboratory.  

The scientists fabricated blood and saliva samples containing DNA from a person other than the donor of the blood and saliva. They also showed that if they had access to a DNA profile in a database, they could construct a sample of DNA to match that profile without obtaining any tissue from that person.

Matter of fact, Doctor Dan Frumkin lead scientist and lead author of the paper stated  the process for synthesizing DNA (fake DNA) was so easy even an undergraduate student could accomplish the task with basic instruments.   

Can we trust the government? Since DNA can be manufactured to fit the crime, the integrity of the forensic scientist has a much greater weight. The answer maybe, No! It appears in the State of Colorado a forensic scientist with the Colorado Bureau of Investigation had been falsifying DNA on sex cases for decades. On February 23 2024 Welding County Colorado announced it had fired another DNA Analyst who worked the Northern Colorado Regional Forensic Lab for just over ten years. How many innocent men were convicted of sex crimes because of her work? In addition, from August 1988 to June 2002 a Polymerase Chain Reaction (PCR) Biologist from the DNA analysis laboratory of the Federal Bureau of Investigations (FBI) was engaged in misconduct during laboratory testing that resulted in her criminal conviction. The falsification of documents has gotten so bad Virginia Beach police have been caught using forged DNA analysis to coax a suspect into a false confession or intimidate someone into a plea bargain agreement. Knowing that just about every crime holds a felony count, browbeating some innocent person into accepting a bargain wouldn’t be hard to do.  It appears that DNA is no longer trusted as proof positive evidence.

The Kohberger case is unique. The only thing linking Mr. Kohberger to the crime is a speck of DNA on a knife sheive. A knife Sheive that could have been deposited at the crime scene by anyone during or before the 8 hour interlude from the time the crime is suspected  to have been committed. The only eye witness to the crime did not report the person she saw during the crime  to have had a knife or weapon of any kind. No DNA sample has been found anywhere else.  Not in Mr. Kohbers car, house, office, nowhere has a DNA link been established. The open air question remains, did the forensic analysis use reverse engineering to manufacture a fake DNA sample or, much worse, improperly handle the DNA analysis, or maybe an undergraduate student? Berry Scheck author of the Innocence Project made these statements on  Death Penalty Information center regarding the Houston, Tx DNA laboratory scandal in 2004,

 We already know that they couldn’t do DNA testing properly. Now we have a scandal that calls into question many thousands more cases. And this jurisdiction has produced more executions than any other county in America.
