Inmate's Death Raises Questions About Controversial Prison Procedure (GRAPHIC VIDEO)

In 2010, Charles Toll, a mentally ill inmate at a Tennessee prison, died following a controversial procedure called a cell extraction.

After Toll threw liquid on a corrections officer, his cell was ordered searched while he was handcuffed and pushed face-down on the floor. He was forcibly removed and later died. An autopsy gave the cause of death as asphyxiation.

The officers involved were never charged and prison officials have even lauded the fatal incident as a good example of what a cell extraction should look like.

Toll's family is now fighting to have his story told. An exclusive investigation by The New York Times sheds light on the deadly routine, the circumstances of Toll's death, and his family's fight for justice.
