Texas officials release video showing jail hall leading to Sandra Bland's cell on day she died

HEMPSTEAD, Texas - Authorities in Texas have released a video covering the three hours before Sandra Bland was found dead in her jail cell.

A transcript of the video released Monday by the Waller County sheriff's department shows that for more than 90 minutes before the 28-year-old was found dead, there was no movement in the hallway leading to her cell. In part of the video, you can see down the jail corridor as authorities realized she wasn't breathing.

Bland was arrested July 10 after officials said she became uncooperative during a traffic stop. She was found dead in her cell on July 13. Authorities say Bland hanged herself, but her family questions that account.

Meanwhile, a dashcam video of the traffic stop has yet to be publicly released.
