Cryptic Killers Murder in Market Hill

In 1965, my Uncle Percy admitted to killing a journalist called Randall Tomlinson by pushing him in front of a train. Following his confession, Uncle Percy was incarcerated until his release in 1990. After Percy was freed, I developed a close bond with him, and it became increasingly apparent to me that he might have admitted to a crime he didn't commit. Unfortunately, Percy recently passed away without taking the opportunity to restore our family’s reputation, which these events had tarnished for decades. Motivated to uncover the truth, I've begun to delve deeper into his case, convinced there is more to the story than meets the eye. I now need your help as a private detective to identify the real killer. This case file contains photographs, statements, police reports, and newspaper articles. My online storage drive houses further evidence, too. Please examine the materials provided to determine who was behind this heinous act.
