Thallium The Poisoners Poison and the case of a large quantity of it missing in Penn Hills

I have driven down Sandy Creek road many times in Penn Hills over the years past several small manufacturing plants and assorted business  and never really paid attention to the small place along the road near the top where Verona Road meets . Then one afternoon in 2009  while driving by this small plant there where all kind of environmental and emergency vehicles sitting outside. OK something going on will have to watch the news this evening .

Former Industrial coatings plant. 

Well it ends up there is a major concern seems 2 gallons of Thallium the Poisoners Poison as it is known  from mystery writers novels is missing from the former industrial diamond  powders processing facility.  which had closed in 2003  a relative reported it missing and they where ready at one point to break up a cement slab in drive way to see if it had been disposed of there. But after an extensive search and back round investigation of the relative of the plant they pretty much are sure he is just making up a story as he has a history of questionable activity's in his life. Yet he still claims it is missing and it may well be missing as there does not appear to be any records as to how it was disposed of when the plant closed along with a bunch of other dangerous items. Too many times things get spilled on the ground or buried  and forgotten which could be very bad situation with this product which could poison the entire town if it gets in the water table .

The building has since become headquarters for a company which remodels homes for flipping purposes. 

but the case is still open.
