Activism In 2014, Pérez founded Cabaña de Sabiduría a women's shelter in Tlalmanalco. The shelter provided support to female victims of gender-based and institutional violence.

Pérez went on to campaign for the Mexican government to address issues of femicide in Mexico. On 22 February 2019, she participated in the first forum concerning the victims of crimes against humanity at the Senate of the Republic; in April, she participated in a 50-day sit-in in front of the National Palace to protest increasing rates of femicide during the presidency of Andrés Manuel López Obrador. During the protest, she stood in front of López Obrador's car in an attempt to give him letter demanding he facilitate a meeting between protesters and the Secretary of the Interior, Olga Sánchez Cordero, to discuss violence against women. On 11 April, Pérez took part in a discussion at the Chamber of Deputies in which she called for femicide to be officially recognised as a public health, national security, and social justice state of emergency.

Disappearance and death Pérez was last seen in early March 2021 in the Los Volcanes area of Santa María, Tlalmanalco; she had informed her mother Concepción that she was going to work at Cabaña de la Sabiduría.
