Investigating Twins DNA and Fingerprint Analysis

There is always controversy when twins are involved in criminal investigations. The case of Donald Smith from Georgia is a prime example of how DNA in twins can often cloud judgment of the authorities. But a fingerprint analysis will always prevail with the most accurate result.

It was in 2008 when police in Gwinnett, Georgia arrested Donald Smith for carjacking and murder. At the time there was no doubt that the police had caught their man. Witnesses identified him, a nearby security camera identified Donald Smith steeling the car and DNA evidence found at the scene matched Donalds DNA. But with all this, Donald insisted they had the wrong guy and that the crime must’ve been committed by his twin brother. That old excuse? Not this time.

Following a detailed fingerprint analysis of the crime scene it was found that none of the fingerprints matched Donald Smith. Upon further investigation it was found that the fingerprints were from his brother Ronald. It turns out that Donald did infact have an identical twin brother and therefore shared DNA but not fingerprints. Donald was telling the truth and brother quickly Ronald found himself in custody.
