Richard Dick Kallman, 46, was killed on February 22, 1980, inside his Manhattan townhouse, which also served as the showroom for his antiques and art business. He lived there with his partner and used the space to display and sell paintings, jewelry, and rare furnishings—items investigators said were taken in the attack and never recovered.

Police described the incident as an armed robbery in which intruders forced their way into the home. The attack left Kallman and Steven Szladek shot to death while the thieves ransacked the residence. Some accounts say three perpetrators were involved; reporting and later accounts focus on Charles Lonnie Grosso of Queens as the person arrested and convicted in connection with the killings. Court coverage places a jury verdict and a 25 years to life sentence in 1981.
