I originally found my court case in a digitized image of an old NL newspaper. It is on the googld news site:
http://news.google.com/newspapers?id=wu ... 20,1475672The link above takes you to a newspaper dated 1814, but it gets you into the body of the newspapers and you can work your way around from there.
It takes a bit of time to work out how to navigate the site and choose the paper you are looking for (there are literally thousands); but as you have a date to work from, you could move forward a month and see if the trial was reported in the newspaper. As it was a murder trial, I would guess it would be in the papers.
Good hunting!
