The date between Erika Gaytan and Ricardo Marquez to a concert ended with Gaytan not returning home. Her family immediately believed something terrible happened to the 29-year-old woman; her mother said there was no way she would abandon her 7-year-old son. Continuous searches throughout El Paso – including in the sprawling desert east of the city – did not yield her remains. Despite her body not being found and a cause of death unknown, police arrested and charged Marquez with her murder. Could the 28-year-old’s behavior leading up to and after Gaytan’s disappearance be enough to convince a jury he is a killer?
