S1E280: Renata finds a key witness

Renata ( Susana Hidalgo ) was threatened with her son's safety two years ago. That fear persisted, which is why she refused to participate in the collective complaint that Vanessa ( Begoña Basauri ) and Jessica ( Ignacia Sepúlveda ) were preparing. Shortly afterward, the prosecutor reconsidered and changed her mind. She even traveled to Argentina to find the key person in the murder of Bernardita Vial ( Catalina Guerra ).
