Protesters Gather for Sandra Bland March

Sandra Bland

Texas authorities released several hours of footage showing Sandra Bland during her three days in jail in hopes of dispelling rumors that she was dead before arriving there.

Waller County Judge Trey Duhon said such conspiracy theories — including one that Bland’s mug shot was taken after she died, have prompted death threats against officials.

“Because of some of the things that’s gone out on social media, this county has been literally attacked,” he said at a news conference, according to the Chicago Tribune. “Sandra Bland was alive and well.”

The video released shows her arriving at the jail after being detained during a routine traffic stop. She can be seen filling out forms, making phone calls, getting her mug shot taken, sleeping in her cell and being taken in and out.

Authorities say Bland hanged herself with a garbage bag, a finding that her family has questioned.

In Chicago, protesters demonstrated on the Michigan Avenue Bridge during a rally for Sandra Bland on Tuesday.

The activists carried a lighted “say her name” sign at the event, organized by the Chicago Light Brigade, the Chicago Taskforce on Violence Against Girls and Young Women and others.

Outside attorneys will assist Waller County District Attorney Elton Mathis in investigating Bland’s death.

The Texas Rangers and the FBI are investigating the case.
