On Saturday afternoon, March 28, 2020, 69-year-old Mark Vuono was killed during a robbery at his Marco Jewelers store in Stamford, Connecticut. A customer entering the shop at about 2:48 p.m. discovered the scene and summoned police. First responders found Vuono on the floor in front of an open safe with a fatal gunshot wound; the Office of the Chief Medical Examiner ruled the death a homicide from a gunshot to the head.

Surveillance and subsequent investigation identified three suspects from New York. Paul Tony Pro Prosano, 59, drove Thomas Liberatore, 62, and Robert Rallo, 56, to the store in a black Jaguar. According to footage, Rallo struggled with Vuono while Liberatore took jewelry from display cases; during the struggle Rallo reached into the safe, seized Vuono’s .357 Magnum revolver and shot him. The robbers fled with an estimated $360,000 to $430,000 in jewelry.

Law enforcement tracked the vehicles to Staten Island; a March 31 vehicle pursuit led to crashes and the apprehension of Prosano and Rallo, and Liberatore was arrested on April 1, 2020. Significant amounts of the stolen jewelry were recovered from the suspects’ vehicles and Prosano’s residence. Does anyone have information about Vuono’s store, customers, or activity that afternoon that could add to the record?
