JoAnn C. Thomas was 38 when she was killed in Springfield, Massachusetts in the autumn of 1997. She was discovered in her apartment after a violent struggle; investigators say she had been sexually assaulted and strangled. Her death was one of several brutal murders of vulnerable women in the city during 1995–1998.

Evidence recovered from Thomas’s apartment included fingerprints and DNA that later helped link the case to Alfred Gaynor. Gaynor was arrested in 1998, and by May 2000 authorities had secured convictions in multiple killings, including Thomas’s, resulting in four life sentences without parole.
