Senior Lecturer in Forensic Science, Dr Sarah Fieldhouse, has written a piece for The Conversation about discovering a way to recover DNA from fingerprints without destroying them.
“Fingerprints hold a lot more information than you might realise. They don’t just provide a pattern with which to identify people. They can also contain DNA. And as neither DNA nor fingerprints are infallible ways of working out who was at a location, combining both pieces of evidence could be vital for investigators.
