There are thousands of anecdotal reports of this, just as there are thousands of anecdotal reports of alien abduction and satanic ritual abuse, but as Sydney Brandon, M.D., et al, observe in their recent report, there is not even a single case in which this has been proven to have occurred. Even if isolated cases are ultimately proven, the extremely low ratio of confirmed cases to allegations will continue to make claims of massive repression highly suspect. Always keep in mind the need to assess credibility of the accuser. A pattern of steadily increasing allegations over time is a warning sign. This is a warning sign that the accuser may be unknowingly confabulating false stories which he or she honestly believes to be true.
Early assumptions can bias the interpretation of evidence found later.
If you make any assumptions early on during an investigation, remain conscious of those assumptions and constantly question whether they need to be changed in light of evidence discovered later. If you make a hypothesis, don't make the classic mistake of accepting all confirmatory evidence and dismissing all contradictory evidence. Keep an open mind throughout the investigation and constantly reexamine earlier assumptions and conclusions on the basis of evidence found later. A wrongful conviction is a triple injustice. If you convict the wrong person of an actual crime, then an innocent person goes to prison, the actual criminal remains at large and free to harm others, and public confidence in the legal system will be undermined.
