Question: How does Eddie get away with the apparent murder of the blonde woman in the apartment? I gather that even he doesn't know whether it was him or not but surely the Police would want to at least call him in for questioning at some point? And if it was him, surely, in that situation, it would be difficult to get away without leaving any evidence?
Answer: There was no mention of physical evidence like hairs or fibres, the only evidence the police had was an eye-witness placing Eddie at the scene at the time the murder occurred; the eye-witness failed to I.D. Eddie in the line-up he was called to at the police station so Eddie was released, as the police had no case.
Answer: It was mentioned that the room was wiped clean after the murder. It was probably Atwood who set it all up because he was on NZT and needed some more.
Answer: Did you watch the movie? Lol... Eddie was called in and questioned about the murder. He was able to beat the case because the eyewitness couldn't pick him out of a line-up. Remember, his lawyer arranged to have a line-up full of men that looked just like Eddie.
The point of a line-up is to make everyone look similar to the actual suspect. So, the lawyer didn't do anything shady, and it would have been the police's job to have similar-looking people. A line-up of a mix of people is kind of a movie/TV trope, and the film implying the lawyer rigged the lineup fits into that trope.
Answer: Although there is no definitive proof, I believe the killer to be Atwood's henchman. During the trip scene we see him following Eddie and the Blonde to their room and although it comes off as an illusion there's no reason it cannot be real. This alone is not enough to say for certain but the main reason I point to the henchman is because of how the story plays out following the murder. Eddie is by an eyewitness (probably someone working for Atwood if not the actual killer) who tells the police about him and as a result he is called into questioning. Because of the inquiry Eddie hires "the best lawyer in the city" who as we know is under Atwood's thumb. It is during this line of questioning the lawyer is able to go into Eddie's jacket and steal his NZT. None of these things would have happened had the Blonde never been killed.
