Sandra comes from a poor background. Her husband died while working as a constructor and she grew Rebeca on her own. She used to run a haberdashery, but she was quickly forced to close it due to a shopping mall which opened in their neighborhood. Then she searched for a new business, and entered the drug dealing world.
After moving to the new house, she enrolled Rebeca in Las Encinas.
