In 1989, Texas executed Carlos DeLuna, a poor Hispanic man with childlike intelligence, for the murder of Wanda Lopez, a convenience store clerk. His execution passed unnoticed for years until a team of Columbia Law School faculty and students almost accidentally chose to investigate his case and found that DeLuna almost certainly was innocent. This book and its website (thewrongcarlos.net) reproduce law-enforcement, crime lab, lawyer, court, social service, media, and witness records, as well as court transcripts, photographs, radio traffic, and audio and videotaped interviews, documenting one of the most comprehensive investigations into a criminal case in U.S. history.
