Not true. Things have improved vastly in the health administration sector, especially when it comes to records. Corruption is indeed rampant but I think most Indians themselves have a very Bollywood-y idea about how things happen outside of their circle. So for a foreign official, outright faking it would be tough, until its somewhere deep in the rural parts (with little connection to the outside world). I think its more plausible that he committed suicide and the records are being altered, not faked.

Source: I have family working in this sector. Shit is difficult, especially if you are a foreign personal.
