Lincoln Rhyme (Denzel Washington), once field forensics specialist extrordinaire, is now a quadropelegic. He has to depend on his nurse (Queen Latifah) and his high-tech room set-up for everything. When a series of grisly New York killings take on a twist, Rhyme must use the able-bodied Amelia Donohughy (Angelina Jolie) to help him to race against time to before the Bone Collector claims his next victim.

Amelia: I can't do this.
Lincoln Rhyme: You can do it. Yes, you can. Yesterday you stopped a train. You can do anything you want when you put your mind to it.
Amelia: Don't work me, Rhyme... Just tell me what to do next.
Lincoln Rhyme: Very slowly... walk the grid... one foot in front of the other. I want you to look around you now. Remember... crime scenes are three-dimensional... floors, walls and ceilings.
Trivia: The Director, Phillip Noyce, makes a cameo appearance as the man in the bookstore.
Question: Can someone please help? When the killer shows up at Rhyme's place at the end, he explains to him why he did it and how Rhyme did him wrong, but no matter how many times I watch it, I don't understand what exactly happened and how Rhyme was to blame for it?
Chosen answer: The killer used to be a forensic scientist for law enforcement (where or when is never stated). Rhymes testified in court that evidence had been falsified, leading to wrongful prosecutions, the killer was sent to prison for this, where "every day I was brutalised". The killer blamed Rhymes for this, so set out to prove he was better by giving him a series of clues that he (in theory) couldn't solve. It should also be pointed out that Rhymes never met the killer or knew what he looked like.
