What major turning point occurs for the Mirabal family in chapter 9?7

In Chapter Nine, the turning point begins with Leandro's arrest. At Mama's house, Maria Teresa tells Dede that the SIM had broken into their apartment and ransacked it, taking Leandro away. Patria arrives, a complete wreck. Pedrito and Nelson have also been arrested, and their home has been torn apart and burned to the ground. When Dede gets in touch with Minerva, she repots that Manolo was arrested the night before, too. A few days later, Minerva confesses to Dede that she has been diagnosed with tuberculosis and needs money to pay for medications. But before Dede can bring them, Minerva is also taken to prison.
