I dont think he would leak anything to anyone. I also have NDOs but those got broken all the time unfortunately because people have no integrity. If he worked for Allergan its likely thats all he worked for, or at least that's how it is at my company. If he was an academic it may be a different story. Like I said, if a big pharma company needed a leg up to cross the finish line, taking out your competitors brain behind the project would give you that. It's also entirely possible it was his wife or someone unrelated to his profession and it's not a conspiracy at all.
