This thing happens a lot in other fields. For example, once a scientist is discovered to have committed fraud by manipulating a photograph of results in a paper, people immediately start looking at their other papers and find other examples as it is very unlikely that someone will do this only once.

In general it seems regular pattern in fraud. All sorts and specially financial. Things start small and then they are either repeated or grown in scale and eventually are caught. There is probably lot of one time fraud that does not get caught. But serial cases are the pattern when caught.
