Hi, I’m looking for a movie that I watched around 12 years ago. I’m relatively sure that it is an american movie from the 1990s up to the early 2000s.

The main plot is that a young man (maybe a journalist?) reconstructs a murder of a young poor woman. He gets the necessary information about the murder from the media and tries to look like the murderer by visiting the crime scene and buying specific products. I remember one specific detail namely that he bought rare sneakers or shoes that the murderer had worn. Lateron his approach leads to a trial where he is sentenced to death. One specific evidence saves him from death penalty at the last moment.
At the end of the movie there is a plot twist. The girlfriend of the acquitted man is sitting in the bed and sees an interview on TV, in which her boyfriend interviews a woman. Although the interviewed woman can not be seen, the girlfriend realises that this woman is the murdered woman. This proves that her boyfriend who had allegedly reconstructed the murder, was the real murderer.

I’m sorry that I only remember some parts of the plot. Unfortunately i can’t remeber any actors. Nevertheless I hope someone can help me to find the movie title. 🙂
