On the morning of February 22, 1980, 26-year-old Stephen Szladek and his partner, former television actor Richard Kallman were shot and killed in their Manhattan apartment. The two men operated an antiques and art dealership from their home and were targeted in what investigators described as a premeditated robbery aimed at their collection of antiques, jewelry, and art.

Authorities arrested Charles Lonnie Grosso of Queens and charged him in the double homicide. Grosso was convicted at trial and sentenced to 25 years to life. A portion of the stolen valuables was never recovered, leaving unanswered questions about what was taken and where it went.

Did anyone in New York at the time have information about the couple’s inventory or the missing items?
