How could local (country level) branch of Mitsuhama organize this? (Content Warning: suicide)

This may feel a little bit out of context, I'm cutting out a lot that I don't want to influence the ideas.

Local MCT Head of Security is supposed to commit seppuku. My players are hired to fake it and extract him. Extracting the family too is bonus pay. It is supposed to look as if he does it and family disappears. If MCT doesn't suspect anything, it won't be looking for the family afterwards.
I am wondering what are acceptable ways it could be organized but can't find the details in the books.

• a meeting in MCT HQ - will be hard to fake and extract, but if they figure it out, MCT will not be suspecting anything
• in their home, recorded and sent to local CEO - I think MCT should accept this as valid, making the whole thing easier, as long as nothing looks weird

Do you have any other ideas?

Of course, the question why fake it instead of just extracting the whole family at once is valid, but at this point this is a question to my players. How thorough do they want to be.
