In Carpinteria, California police arrested 61-year-old registered sex offender Glenn Sherman Merrill. Merrill allegedly posted an ad on craigslist for a home health aide. An 18-year-old girl responded to the ad and when she was taking care of Merrill he allegedly exposed himself to the girl and asked her to assist him with *ahem* something else.
She told the cops who locked Merrill up for failure to report and I would assume the exposure charge as well.
It just goes to show that apparently there is no section on craigslist that is free from criminals and predators.
