Yes, it is an unfortunate coincidence of names.
Here are two photos of Betty Harrison, taken at the beginning of the trial in late November. The first shows her arriving on November 23th:(Image reproduced courtesy of the London Free Press Collection of Photographic Negatives, the University of Western Ontario Archives, November 23, 1970.)
She's the one in the middle with the folder over her face.
And when she arrives on November 25th:(Image reproduced courtesy of the London Free Press Collection of Photographic Negatives, the University of Western Ontario Archives, November 25, 1970.)
As one can see, there's a pretty obvious reason why neither of these images were ever used in the Free Press coverage of the trial. Betty Harrison clearly did not want her picture taken. Of the six photos taken of the woman on the two days, these are the best images to be had. One can imagine the photographer's frustration of not getting a quality shot of the most important Crown witness.
I'm not sure who the man ahead and the woman behind are. The gentleman appears to be an official escort, possibly a plainclothes police officer? And I suspect the woman behind is a friend of Betty Harrison's. Anyone know?
(Also, as an aside, note that in the first picture we get a good shot of Judge Colter's car.)
In any event, what I get from these two images, and the sequences they come from, is that Betty Harrison had no interest in having her picture in the paper. She's transferred her folder (what might this contain?) to the hand on whatever side the photographer was stationed in an effort block her face, and keeps her head down with no interest in meeting anyone's gaze. To me, this suggests that she was definitely no publicity-seeker, and was reluctantly involved in this process, rather than gaining any sort of pleasure or enjoying any notoriety from the experience.
What we are left with, as the face for this woman, is a portrait from a LFP court sketch artist, which one has to take on faith for an accurate likeness:
The image seems to depict a rather plain-looking woman, with slightly unkempt hair who hasn't spent a lot of time on her appearance. There is a clear element of consternation in the pronounced frown. Apparently, the court had to be recessed at least twice to allow her to compose herself.
It would be nice to have a transcript of the trial available, to find out at what specific points those occurred (among other things). Yet, none so far have surfaced. Unfortunately, the crown only keeps transcripts if there are plans to appeal the verdict, and in this case, they didn't.
If anyone has any ideas where another image of Betty Harrison, or a surviving transcript, might be found, feel free to chime in.
