Who killed Marsha P Johnson? When the beloved, self-described "street queen" of NY's gay ghetto was found floating in the Hudson River in 1992, the NYPD chalked it up as a suicide and refused to investigate. However, as shown in Academy Award nominated director and journalist David France's new film, it's a decision many questioned.

Having played a pivotal role in the previous year's Stonewall Riots, in 1970, Johnson and fellow trans icon Sylvia Rivera formed the world's first trans-rights organization, STAR (Street Transvestites Action Revolutionaries). And despite their many challenges over the years - homelessness, illness, alcoholism - Marsha and Sylvia ignited a powerful and lasting civil rights movement for gender nonconforming people.
