Its a Fancy Coffee House now but in the 80's it was a seedy bar where a deadly drug China White was dealt which helped to kill 22 individuals.

Its called China White  a powerful synthetic  mix of Heroin and Fenteynyl  .
one Pittsburgh based Chemist in Aspinwall would use his skills to make it and end up killing 22 and overdosing many more.

The outbreak started and was traced  to  its distribution  in what was once a  nondescript  Seedy Bar on Pittsburgh's North Side now a coffee shop and Deli  at Federal and West streets  where people get there morning Caffeine fix  a perfect place to distribute drugs as the bar had several ways in and out and many twists and turns inside. When you rode by in summer the doors where open and you could look inside its dark interior

By at  the time it was over in 1988  a chemist who was making  the drug at his residence and distributing the drug  from this former bar was arrested at his Aspinwall residence after   22 deaths where attributed to the deadly wave of overdoses as junkies flocked to try the new dangerous drug.

I was doing work and teaching  on he North Side at this time and saw many times Junkies being picked up by medics   in the back alleys and parking lots and along East Ohio and federal after passing out from a fix. 

Thankfully 2 outstanding Pittsburgh Narcotic Detectives I once meet  Barry and Fox

where able to infiltrate and break this case wide open with help from the DEA and needless to say it came as a shock when police surrounded a residence in quiet and upscale community of Aspinwall a few miles up the Allegheny River from Pittsburgh.

As people come in to get there daily morning cup of Jo   these days many would be shocked to know this deadly wave of drug overdoses started right there on that corner.
