Did Harry Really see Lily die?

I've seen a lot of people saying that he did.  But I wonder.  We know 
he heard her cry out, then a flash of green light.  Does it ever say 
that Harry saw her body drop, or that he saw her laying there dead?  
I've always sort of thought that Harry's memory stops at the light, 
then his mind connects the two occurances together and fills in the 
gaps.
