For over a century, the true identity of Jack the Ripper has been one of history’s most haunting mysteries. But now, new DNA evidence has finally unmasked him… But why was he never brought to justice? And what led him to spend the rest of his days locked away in an asylum?

Arguably some of the darkest crimes were the work of repeating offenders - serial killers who left their stain on the world over and over again with each horrifying act. Some of these criminals were caught and tried for their crimes, while others remained anonymous and at large. Among them all, there also seems to be a number of killers who continue their reign of terror, even after their own deaths.
