The serial killer du jour targets blondes in their 30's and 40's or so. We see him early on and he clearly has OCD. One symptom is that he makes clicks with his tongue a lot. He has sent a videotape of one of his killings to the police in which his hand is shown writing HELP. You also see that an upcoming date is circled in the victim's dayplanner (by the killer it turns out--some left/right handed stuff here)--which the team takes to mean is the date of his next kill. However he generally kills about once a year so this is puzzling. He wears a minicam in his glasses to film his kills and the approach to them.Originally Posted by ilovefootball25;3430328;
Eventually we find out that the killer saw and filmed his mother's death by stabbing as a child---he was hiding in a closet I think, with louvered doors, and the mom had been messing around and was caught. Near the anniversary of her death he kills a similar looking woman. Anyway, one time he killed the woman and then her blind son came out into the yard looking for her--the kid makes clicks as a form of echo location (like a bat his foster/soon to be adoptive mom says) to avoid using a cane. The killer is upset that again a child is witness to a mom's death. He becomes a "big brother" to the kid and they bond. The date is the kid's birthday and the killer sneaks him out of the house to take him to the fair to ride a ferris wheel--the two of them have been building a ferris wheel model. The mom won't let him take the kid anywhere alone (and I guess he doesn't want to take the mom, too).
The team is gradually figuring stuff out, but while they are a former co-worker comes to the killer's apt., much to his dismay, to flirt with him and ask him to film someone's wedding. While she is there she sees a sketch of him on TV (in the film he sent in you see he has interacted with a passing couple and they gave the sketch details), so he kills her, even though she is young and black--a different pattern. This helps them figure out who the killer is as she knew him. During this they visit the kid and his foster mom, to talk to him about the killer and what happened when his mom died, as he is the only witness they have.
Anyway, just before the birthday the killer is walking in a tough part of town (not sure why) and two hoods try to hold him up--he stabs one and is shot by him as he falls, and the other runs off and calls the cops. He still takes the kid on the ferris wheel adventure, but is clearly in physical trouble. On the way there the kid says he wishes the killer had killed him, too. While they are sitting stopped at the top of the wheel they talk and the killer says to never ever wish he was dead, that's he's special, that he has helped the killer "to see" (that what he was doing was wrong--hence the cry for help to stop since his OCD won't let him stop doing it). Then the killer keels over dead. The team has reached the wheel and they bring it down. The kid is gradually realizing that his pal killed his mom. All very sad.
Feel free to add if I left out something!
