It's a bit of a mystery. Some people claim it's true, while others have doubts. It depends on the sources and the credibility of the information available.
Lester Ballard is a character whose true story could involve a lot of aspects. Maybe he's from a southern - style setting. He could be someone who has had a hard time fitting into society, and his story might be one of struggle, survival, and the consequences of his actions. For example, he might have faced poverty or some form of social ostracism which led to his actions in the story.
I'm not sure specifically who Jon Franklin is without more context. He could be an ordinary person with a passion for sharing true stories, or perhaps a professional storyteller, journalist, or writer.
The Lester Ballard true story could potentially have many main events. It might start with his early life, like his childhood experiences that shaped him. If he grew up in a poor family, that could lead to certain actions later on. Maybe he got into trouble with the law early on, which set him on a path of more problems. There could be events where he tried to find love or friendship but was rejected. His interactions with the local economy, such as trying to make a living during tough times, would also be important events. And if there was a climax in his story, like a big confrontation or a life - changing decision, that would be a major part of the main events.
It depends. Some parts of Franklin might be based on real events or people, but it could also have fictional elements added for entertainment purposes.
I don't think Franklin Murray is part of DC Comics. DC has a vast array of characters, but this name doesn't ring a bell among the popular or established ones.
