AI Helps Release Man After 23 Years

Why this is here: CaseText analyzed 14,000 pages of documents to help uncover overlooked evidence in Willie Nash’s case, a process that would have taken human reviewers far longer.

The Innocence Project uses artificial intelligence to review evidence in the 1996 murder of a woman in Louisiana. Willie Nash served 23 years of a life sentence for this crime before his conviction overturned in March 2024. The AI tool, called CaseText, quickly analyzed roughly 14,000 pages of documents.

Investigators initially focused on Nash due to a partial fingerprint found at the scene. CaseText identified inconsistencies in the original police investigation.

It revealed that detectives did not fully investigate other potential suspects or follow up on leads pointing away from Nash. This included a second fingerprint at the scene that belonged to someone else.

The AI flagged this overlooked evidence, prompting a re-examination of the case. Attorneys then presented this new information to a judge, leading to Nash’s release.

While this technology offers a faster way to review evidence, access remains limited. The Innocence Project continues to advocate for broader implementation and address concerns about algorithmic bias in these tools.
