A man in the US has been exonerated after serving 20 years in prison for a crime he did not commit, thanks to the help of genetic genealogy - a technique that compares unknown DNA evidence to public genetic databases to identify suspects through their family members.
Christopher Tapp was sentenced in 1998 for the rape and murder of Idaho teenager Angie Dodge - despite the fact his DNA did not match evidence found at the crime scene.
Instead, he had been convicted based on a confession he late retracted, along with the theory that multiple people had been involved in the crime.
Decades after proclaiming his innocence - and saying his confession was coerced - Tapp was finally exonerated on Wednesday after genetic genealogy was used to find a new suspect in Dodge's murder.
As he left court, Tapp told reporters: "I hope that things get learned from this mistake and I hope things get changed."
He continued: "I'm glad I was able to come out the other end and still smile and still be happy.
