Cyclops' Death in X3

[AvengingLeague]

In X-Men: The Last Stand Jean Grey(or rather Dark Phoenix) had killed Scott Summers(Cyclops) off-screen very early in the film. I'm wondering how exactly she accomplished this? I mean, how exactly did she kill him? I am wondering how he could have died.

She was constantly demolecularizing(?) crap. I assume that's how she did it.
