Every year, tens of thousands of women and girls disappear in the U.S. Each disappearance is a tragedy, but for missing Black people, their cases remain unsolved four times longer than those of white people. Experts say that’s due to a lack of media attention, slower police responses, and communities that fail to push for answers. Soledad O’Brien serves as an executive producer of Black and Missing, a 4 part HBO documentary series focused on those unsolved cases. Ahead of its November 23 debut, she speaks with Derrica and Natalie Wilson. They started the Black and Missing Foundation in 2008 to find answers for grieving families.
