, the most recent annual memorial held for Santos was in July 2020. The event involved speakers reading and reflecting on the names of individuals killed by police, including Michael Morehead (killed by Cain in 1970), Tamir Rice and George Floyd. Dallas police chief Ulysha Reneé Hall made a surprise appearance at the 2020 memorial, and did not speak at the podium, but approached and told Santos' mother that the Dallas Police Department was committed to "being a different police department." One activist speaking at the memorial addressed Chief Hall in the crowd, telling her, "I’m calling you out. You came to this memorial and we are glad you are here, but we need your help."
