LIVINGSTON, Texas – This story was originally published by our partners at the Texas Tribune. In 20 days, state authorities are scheduled to drive death row inmate Ivan Cantu from the Allan B. Polunsky Unit, past freshly built vacation homes on Lake Livingston, along wooded East Texas roads, to the notorious, red-bricked Huntsville Unit, where Texas will execute him. That is if Cantu’s third execution date isn’t canceled like the two before.
