Since we have a page on Suicides we might as well have a page on Murders.
Lucien Carr
Lucien Carr was a Columbia student notable for being an associate of a number of beat authors, for committing an infamous murder, and for siring novelist Caleb Carr. While at Columbia, he was a roommate of Allen Ginsburg's and is credited with introducing Jack Kerouac, Allen Ginsburg, and William S. Burroughs to each other.
While a student at Columbia, Carr murdered a man named David Kammerer. Carr was close friends with the man, and had known him from his youth in St. Louis (Kammerer was Carr's Scoutmaster.) Apparently, Kammerer had been making sexual advances on Carr for several years and had even followed him to New York from St. Louis.
On the morning of August 13, 1944 around 3AM, Carr and Kammerer were drinking in Riverside Park. Kammerer made advances on Carr. In self-defense, Carr stabbed Kammerer to death. He subsequently tied Kammerer's hands and feet together with shoelaces, filled his pockets with rocks, and threw his dead body in the Hudson River. He confessed what he had done to Jack Kerouac, who was in turn detained by police for being a material witness. Carr later turned himself in. He was sentenced to 20 years for the murder, but was released after 2 years.
