Is it true he kept the heads to beat them?

It's rly intriguing that cops were able to find skulls and not find bodies. If any, I'd expect the opposite.

This movie says that Ted kept the heads (and not the skulls), to beat them at home and feel powerful, and then threw them away at the same time.

So, is it true? did he say that? or was it created in this movie as a plausible explanation?

I also think it interesting how this movie also shows Ted as a mediocre guy. I expect to see him as a charming one, who easily brings girls willingly to their deaths.

There's another movie that denies that, showing the attraction as if the girls just wanted to help a random guy with hurt arm or leg, and not properly interested in him. As if they'd just help him get to his car then move their way, but he beats them first.

This movie goes deeper, saying that he didn't wanna sympathise with the girls. He'd not seduce them into his car, take them away while talking, and only then beat them. Instead, the movie says he beat them first and carried them into the car, and he didn't wanna talk to them. This of course breaks the image of a charming murderer, and suggests that image was just created by him.

For sure, it's disturbing to the society think that a charming seductive guy could be a murderer of girls, and even more think that girls would fall in love for a murderer. Still, even after arrested and charged, a lot of girls mailed him and said they love him. If so many girls took the effort to do that, I suppose many more felt that way without saying it explicitly.
