A few years ago, Antonin Scalia, one of the nine justices on the US supreme court, made a bold statement. There has not been, he said, "a single case – not one – in which it is clear that a person was executed for a crime he did not commit. If such an event had occurred … the innocent's name would be shouted from the rooftops."

Scalia may have to eat his words. It is now clear that a person was executed for a crime he did not commit, and his name – Carlos DeLuna – is being shouted from the rooftops of the Columbia Human Rights Law Review. The august journal has cleared its entire spring edition, doubling its normal size to 436 pages, to carry an extraordinary investigation by a Columbia law school professor and his students.

The book sets out in precise and shocking detail how an innocent man was sent to his death on 8 December 1989, courtesy of the state of Texas. Los Tocayos Carlos: An Anatomy of a Wrongful Execution, is based on six years of intensive detective work by Professor James Liebman and 12 students.
