Smart shop owner jailed for murder.

[VincentVan]

For reasons related to his job SWIM regularly follows the evening news from France. Italy and Spain via parabol.
A few moments ago, while he was browsing the drug forum and watching ,in a corner of his monitor, the evening news broadcast from italian state channal RAI2, he heard a newsreport that cathalized his attention: It seems that the owner of a head shop in the southern port city of Bari, has been jailed and charged with murder, for having sold some vegetable´s seeds to a young guy who subsequently died as a result of these seeds´ ingestion. The italian authorities have now been ordered to sieze all specimen of those seeds from all smart shops/head shops all over the country.
Unfortunately I have´nt been able to catch the full name of the plant in question. It was the seeds of a plant whose name was made of two words the second of which was "violacea"; i.e. : seeds of " XXXXXX violacea".
Can anybody figure out what those life-threatening seeds could have been?
Maybe some italian member has heard the news too, or maybe he might have read about it in the papers?
I´m really curious to know what could have killed this poor lad.
Anyone who will provide us with this information will surely receive positive reputation points, and probably not only from me since all clients of this kind of shops would probably be interested in knowing what to stay clear of, in order not to risk their life.
