1994, May 10 / Tengen-Wiechs (Baden-Wuerttemberg) Germany / R/N: In the small town of Tengen-Wiechs, Germany, a 5.6 g of very pure (99.75% enriched) Plutonium-239 was found in the garage of businessman Adolf Jaekle, mixed with Red Mercury. The most likely origin of the material was a Russian weapons laboratory, possibly the Arzamas-16 laboratory near Moscow
