That's just disturbing.
Anyway, this reminds me of an Alfred Hitchcock episode where 2 people plan a murder, and then the one double crosses the other and hides a body in trunk so the other will get caught, and the first will get away scott free. But I'd think the woman would know if she were carrying around an entire human body in her suitcase. It would be rather heavy. Even a baby...ew I don't want to think about that.
