Mexico's top prosecutor said on Wednesday there had been flaws in the investigation of a ranch in the western state of Jalisco, which activists have called a cartel-run "extermination camp," and vowed to uncover the truth of what happened there.

Charred bones and hundreds of articles of clothing and other personal effects were found at a location dubbed by local media as the "ranch of horror."
