The haul was found by a metal detectorist/looter next to a Roman road near Rülzheim and only discovered when he started to try to sell the pieces on the black market. Police are currently investigating.
The German tabloid, the Bild has now identified the metal detector looter as Benny C, 22, from Speyer along with a picture that will do little to dispel illusions of what nighthawks look like. It has the full story here. Focus magazine also has a pickup, here.
