On the evening of June 29, 2022, 20-year-old Azsia Johnson was pushing her three-month-old infant in a stroller near Lexington Avenue and East 95th Street on Manhattan’s Upper East Side when someone approached from behind wearing black and a ski mask and fired a single, point-blank shot that struck her in the head. First responders took Johnson to Metropolitan Hospital, where she died shortly afterward. Her baby was found unharmed in the stroller.

Investigators focused on Johnson’s ex-boyfriend and the child’s father, 22-year-old Isaac Argro. Johnson reportedly sent texts saying she was meeting Argro that evening to work things out. Her mother said Johnson had been a victim of domestic violence and had previously reported an incident in which Argro allegedly pushed her while pregnant; Johnson had been living in a domestic violence shelter. Two days later, on July 1, 2022, Argro was arrested in the Bronx and charged with murder and criminal possession of a weapon. Prosecutors described the killing as a premeditated act of fatal domestic violence; he pleaded not guilty and was held without bail.

Did anyone on the Upper East Side see Johnson and her stroller near East 95th Street that evening or notice a person wearing black and a ski mask in the area?
