I'm not sure exactly where you can watch it. You could try checking on some documentary streaming platforms or searching for it in libraries that have a collection of true - crime or real - life story documentaries.
There are various places it might be available. Some specialized documentary channels might have aired it in the past and could potentially re - air it. Also, certain online video libraries that focus on real - life stories could be a good place to look. It might also be worth reaching out to local community centers or film clubs as they may have information on where to access such stories.
