It's all the same to me but that's often how it goes. Everyone is a sleeper agent until compelled to act by whatever means. Israelis do the same thing under the sayanim program (appeal to loyalty). Malware agents are staged until called upon using the same strategy.
I don't know what motivated this guy's disappearance but you don't get quietly fired, scrubbed from public association and have the FBI raid your apartment when you're a victim of abduction. We know some sort of federal crime took place to justify the raid so my guess is the guy is not an abductee but a fugitive.
