This is a follow up project to what I promised I'd do on my last project:Gwen Stacy:where is she?.This is the explanation that was provided by the comics.So Green Goblin threw her off a bridge,when Spider-man's web touched her it came so fast,that it electrically broke her neck.When he picked her up ,she was dead.If you say"You're wrong because this isn't what happened in the movie" directors change things in books all kinds.But if you do say something like that,tell me an issue where you heard it and I'll do my research,and I'll do a follow up project or delete this one and do what you say.
I did this using what was provided and an image from Google Images.The way she died in the movie is the same as the comics except Green Goblin threw her off the top of a clock tower she falls in the clock tower and the whole she dies is also inside the clock.
