Ok, so i cant think of the name of this movie and its driving me nuts. Its about a guy that's a serial killer and a detective is trying to track him. In one scene the detective is putting push-pins into this map on all the places they've found bodies and when hes done the push-pins form a big spiral on the map. In the ending scene hes in a desert-type place and hes on his knees getting ready to shoot his self and the camera zooms out (above-aerial view) and hes in the middle of a huge spiral (similar to the one on the map). Oh yea! and in one of the first scenes he's shown scraping the pads of his fingers (removing fingerprints) with a pumice stone (i think thats what its called). Anyone know what this movie is? its been driving me nuts and it'd be greatly appreciated if anyone could remember. -thx much
