WATCH: 'Say Her Name: The Life & Death of Sandra Bland' Trailer

HBO has released the trailer for their forthcoming documentary, “Say Her Name: The Life and Death of Sandra Bland.”

It’s been three years since Sandra was arrested during a routine traffic stop and was found dead in her jail cell.

The documentary, set to premiere on December 3 at 10 p.m. on HBO will explore the life of the 28-year-old activist as well as her unexplainable and unacceptable death.

Watch the trailer below.

Sandra Bland’s sisters, Shante Needham and Sharon Cooper, stopped by “The View” on Tuesday to talk about the HBO documentary and how they are still seeking the truth about her death.
