David Kammerer, probably before he met Lucien Carr
Carr was heterosexual but prone to adoration from men, and an older man from St. Louis, David Kammerer, had come to New York to pursue him. One day Kammerer introduced Carr and Ginsberg to another visitor from St. Louis, William S. Burroughs. Burroughs and Kerouac and Ginsberg had finally found each other, and began the weird escapades that would soon exhaust even Lucien Carr’s energy and interest. Carr had his own problems, too. David Kammerer’s obsessive pursuit of him had become so overbearing it was ruining his life, and Kammerer had begun to physically threaten Carr. One day Carr impulsively stabbed Kammerer to death by the Hudson River in Riverside Park, near the Columbia campus.
