New Forensic DNA Technique could Help Solve Sex Crime Cases

New technology that can identify DNA from a single cell could transform crime scene forensics, according to experts, Fiona Stalker and Julie-Anne Barnes reported for BBC Scotland.

Experts say the technique could lead to more convictions in sex crime cases and fewer miscarriages of justice.

Scottish scientists behind the SCAnDi project say the technique can determine both who a DNA sample came from and which part of the body it originated from.

Prosecutors believe that providing juries with DNA evidence supported by a higher level of certainty could help them reach more accurate verdicts. Experts say the technique could lead to more convictions in sex crime cases and fewer miscarriages of justice.

Those behind the technology are now working to make the process robust enough for use in court. Samples collected from crime scenes often contain a mixture of DNA from multiple people.

Scientists believe their new tool can help “unmix” DNA and establish both its source and origin.

Ashley Edwards KC, Scotland’s principal Crown counsel, said the technique could play an important role in prosecuting sex crimes. “Before we run a trial, we will consult with the forensic scientists,” she said.
