Forensic experts scan Pompeii's victims to investigate why they didn't escape the eruption.

Now, forensic experts investigate a group of victims called 'the Fugitives' for the very first time. X-rays reveal ages, injuries suffered, and even artifacts like sandals and jewelry - while the investigation also throws light on why they failed to escape the most famous disaster of the ancient world.
