Whistleblower Tommy Hook was at the Cheeks Night Club in Santa Fe early Sunday morning, reportedly to meet someone else who had information on financial irregularities at Los Alamos. The unknown informant didn't show, but as Hook was leaving he was apparently assaulted in the parking lot. It doesn't look like robbery was the motive, and according to his wife the assailants told Hook, "If you know what's good for you, you'll keep your mouth shut."
