Samira Piscotti, 69, and her 79-year-old husband Italo were killed on July 26, 2013, during a violent incident at the Hialeah apartment building they managed. That night a resident, Pedro Vargas, set a combustible liquid on fire in his unit. When Samira and Italo went to his door to investigate, Vargas opened fire, killing both of them.

The attack was part of a larger shooting spree in which Vargas ultimately killed six people before being shot by police. Investigators reported ongoing disputes between Vargas and the Piscottis that may have contributed to the violence. Vargas was charged with multiple counts of murder; court records described his actions as premeditated and detailed his mental state during proceedings. No other suspects were reported in connection with these deaths.

Did anyone in the building know of recent threats or heated confrontations between tenants and the managers before that night?
