Sure do hope this guy has something to offer the investigators, or he will most likely be accused of being deceptive.
"According to the plea agreement, McLamb must testify "fully and truthfully in any proceeding." To assure his truthfulness, he must submit to polygraph examination whenever federal investigators ask. If he lies or gives incomplete information, the plea agreement could be revoked and prosecutors could recommend that he receive the maximum sentence."
"McLamb's lawyer, David Long of Raleigh, said the agreement was in McLamb's best interests. He said he didn't know whether McLamb had information that would incriminate anyone. "I'm not putting the puzzle pieces together," Long said. "That's up to [federal investigators].""
