It turned out Blauer had been a test subject for the experimental drug tenamfetamine, which is variously described as a mescaline derivative and an analog of MDMA, but which most definitely would not make a depressed man ecstatic. Rather, the goal was to see if it was a "potential dicombobulator [sic] of enemy populations," and it dicombobulated Blauer right into the morgue. He never had any idea he was part of a government study, and neither did his family. They sued the state of New York for negligence, and they weren't told that half of the $18,000 settlement was covered by the federal government in return for New York and the hospital keeping quiet about the experiment.
Then, two decades later, Congress was investigating something totally unrelated when they turned up papers documenting what had really happened to Blauer. His family learned the truth, and after another dozen years of legal wrangling, the case ended up in front of a judge, who made the government pay his daughters another $700,000. Despite the pleadings of the U.S. attorney (one Rudolph Giuliani), the judge ruled that yeah, the government killed Blauer and covered it up. And if you like certainty and/or closure for your stories, you can pretty much stop reading now, because things only get murkier from here.
