In my world there's a company that needs to kidnap a person or a number of persons (reasons are out of scope of this question) and must do this in the way that no one (and I mean: no one) would object, have or ask questions, seek for a missing person etc.
Thus, I'm saying about breaking all that person's family, friends, neighbor and social connections, i.e. "removing" it from the world without creating disturbance and without causing question.
The seized person may really be kidnapped, i.e. not willing to take a part in this process or it can fully cooperate with the company in this process. In both cases the kidnapped person will not seek any chance or way to "get out" (i.e. will be cooperating willingly or unwillingly or will be deluded itself and kept unconscious or not aware of the kidnapping event). So we only need to take care about other persons, not about person in topic.
As chairman of this company, personally involved in "kidnapping", what options do I have?
Things that I considered so far:
Changing facts, social wires, news, faking situations to pronounce person dead. Creating a fake grave for it and let the family and friends believe that it is dead (aka. "La Femme Nikita").
Faking a situation in which person in subject is sent to highest-level jail for ten or twenty years sentence without an ability for a parole and without even a possibility to see anyone.
Faking a letter as written by subject to let family and friends think that this person is "gone" for a longer period of time (years?), i.e. decided to join a contemplative order, some community, sect etc., decided to go for a long-time, world-span trip and deluding family and friends during this period by sending a fake mails, photos and even making fake phone calls (technology allows it in this world).
Not doing anything in preparation stage. Simply kidnapping this person and reacting on all events or situations as they arise (quite very risky?).
Are any of above options plausible? Are there any other options to consider?
Edit: Once people are kidnapped and kept hidden within company's premises (no matter whether willingly or unwillingly) they are kept completely and totally separated from the world. They don't have access to the Internet, telephone nor to any kind of media. So we discuss / cover only their past web-presence. They are not able to create any new Internet/media/world presence.
Edit: As JBH correctly points out there will always be some kind of disturbance created with disappearing of any person (broken social connections). That's fine. I'm only talking about not creating disturbance that can't be handled, i.e. that leads into asking "wrong" questions.
