The Anonymous hacking collective is claiming to have proof that Sandra Bland was murdered while in police custody in a Texas jail.

The group said Texas authorities had failed in their attempt to cover up "a blatant act of crime against an innocent woman."

A video posted by the hacking group on YouTube claims that Bland didn't kill herself, but was a victim of a murder in an attempt to cover up police mistakes.

Anonymous threatened to expose officials' "lies," and called for a day of "Rage for Sandra" on Aug. 8 to demand action against Texas authorities.
