Actually, I was pretty confused about that too. Your reasons are valid, and the only reason i can think of that Nick lied is because his mother was there. The officers believe he killed the John Doe; wouldn't they be happy if he did? Now, they believe he's hiding something, whereas it would be good if they knew he killed him. Medals and stuff is nice (though publicity isn't). Nick could have just lied about his mom being there.
