Reminds me of the Chesire Murders. A guy spotted two women at a supermarket and stalked them to their home because he was attracted to the one on the right.
He raped and killed her. When the police told him she was actually 11, dude lost it. He swore up and down he thought she was an older teen.

Funnily, he killed but didn't rape the 17-year-old sister who looked 30.
