Google “when DNA evidence is wrong”.


Fascinating story. I never realized that DNA could be inadvertently transferred to a crime scene or even to the body of the actual victim.

In this story DNA got transferred via an oxygen-level testing oximeter used by EMTs. So, much for EMTs thoroughly sanitizing their equipment. The DNA found on the fingernails of a murder victim was DNA from a previous innocent patient that had had been treated by the same EMTs. They used the same oximeter on both. WOW. The poor innocent guy had been arrested and was languishing in jail.

Definitely worth reading.
