I live in St Augustine and there has been 3 investigations into this and the media is not telling you everything because the side they present is more juicy
If you get a chance then watch the PBS presentation and tell us where their facts are wrong.
The facts they presented seemed pretty clear.

If you don’t want to view the PBS version, here is the NYTimes version.
More juicy? I don’t know, but St Augustine has a lot to explain.
