Roseann Quinn (November 17, 1944 – January 2, 1973) was an American schoolteacher in New York City who was stabbed to death in 1973 by a man she met at a bar. Her murder inspired Judith Rossner's best-selling 1975 novel Looking for Mr. Goodbar, which was adapted as a 1977 film directed by Richard Brooks and starring Diane Keaton, and its follow-up fact-based semi-sequel for TV, Trackdown: Finding the Goodbar Killer, released six years later in 1983. Quinn's murder also inspired the 1977 account Closing Time: The True Story of the "Goodbar" Murder by New York Times journalist Lacey Fosburgh. The case was the subject of a Season 3 episode 2 of Investigation Discovery's series A Crime to Remember in 2015 ("Last Night Stand"). Early life and education Quinn was born in 1944 in the Bronx, to Irish Americans John and Roseann Quinn. She had two brothers, John and Dennis, and a sister, Donna. When Quinn was 11 years old, her family moved to Mine Hill Township, near Dover, New Jersey; her father was an executive with Bell Laboratories in Parsippany-Troy Hills, New Jersey. When she was 13, Quinn spent a year in the hospital after a back operation (due to scoliosis), which left her with a slight limp. Quinn attended Morris Catholic High School in Denville, New Jersey and graduated in 1962. Her yearbook said she was "Easy to meet ... nice to know." Quinn enrolled at Newark State College (now Kean University) where she majored in elementary education and graduated in 1966. She was on the staff of Independent, the college's student-run newspaper. Later life After graduating, Quinn moved to New York City and taught for three years in Newark, New Jersey. In September 1969, she began teaching at St. Joseph's School for the Deaf in the Bronx, where she taught a class of eight eight-year-olds. She voluntarily stayed after school to help the children often, other teachers recalled. "The students loved her," a spokesman for the school later said. By May 1972, Quinn had moved into a studio apartment at 253 West 72nd Street in Manhattan. The building had been known as the Hotel West Pierre before being converted to apartments four years earlier. According to her acquaintances and neighbors, Quinn would sit by herself and read at bars on the West Side. Police Captain John M. McMahon later said "she was an affable, outgoing, friendly girl.
