So, the [jailhouse]informant, who spoke minimal English, was given a polygraph, but he failed. The FBI test showed the man was "deceptive" when asked if Guandique told him he stabbed Levy and if Guandique received $25,000 for committing the murder.

That's part of the problem with polygraphs...they can't winnow out partial or incomplete truths...for example, if the informant might be implicated or associated with an otherwise truthful answer, it may still display indicators of deception. For example, "Guandique" may have told him about the $25,000 for other reasons, with the Levy story merely as a peripheral issue: i.e., promising to split it with him for a favor, etc.
