New lead emerges in notorious cold case mass murder mystery in Belgium

A decades-old probe into a murderous gang rampage that mystified Belgium could be opened again to chase an unexplored lead, prosecutors said Tuesday.

The cold case known as the "Crazy Killers of Brabant" revolves around two waves of deadly supermarket robberies carried out between 1982 and 1985, killing 28 people including children.

The suspects were reportedly three men who covered themselves in face paint during the raids and became known for their ruthless attacks, the BBC reported. Some of the victims were tortured before being killed.
