The evidence the Columbia team uncovered reveals that Hernandez not only existed but was well known to the police and prosecutors. He had a long history of violent crimes similar to the one for which DeLuna was executed. Families of both Carloses mistook photos of each for the other, and Hernandez's violence continued after DeLuna was put to death. 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.
The result is eye-opening yet may not be unusual. Faulty eyewitness testimony, shoddy legal representation, and prosecutorial misfeasance continue to put innocent people at risk of execution. The principal investigators conclude with novel suggestions for improving accuracy among the police, prosecutors, forensic scientists, and judges.
