I don't know. I guess I just assumed that Barty Jr. (who had a motive)
killed his father as he did in the book. But also, Voldemort is still
in fetal form at this moment (in both film and book), so he couldn't
have just come by and killed Crouch Sr., even if he had a motive. I
guess the forehead clutching indicates Harry's subconscious
realization (or some sort of sixth sense in his scar) that
Crouch!Moody is a Death Eater (or just that something wicked this way
comes)? 

In the book, Voldemort had a motive for wanting Crouch Sr. dead--he
was about to reveal the kidnap/murder plot to DD (fighting the
Imperius Curse to do it). But in the film, Crouch Sr. knows nothing
about the plot or the disguise, so Voldie has no reason to want him
dead, and no way to do it himself even if he did. So I still think it
was his wicked son (scaring him first with the tongue-twitching), but
exactly what's going on is anything but clear.

Just one more problem of many with the film.

Carol, thinking that if it puzzles people who've read the books, it
must *really* puzzle those who haven't
