Stephen Glenn Hassell was 29 and worked as an investment consultant when he was killed on December 15, 1981, in his Manhattan apartment.

Hassell’s murder was one of a series of killings that occurred over about a month in New York City. The same .38 caliber revolver is said to have been used in six killings between December 1981 and January 1982. David Bullock was arrested on January 14, 1982, and later confessed to Hassell’s death and to the other homicides. He pleaded guilty to six counts of second-degree murder and received a 150-year sentence.

Are there additional details about Hassell’s life or the apartment on December 15 that anyone can share?
