Which part???
that she is the only one of her classmates that came out of school that day???
Name?
that she was covered in blood that I’m sure everyone else out there could see???
Who?
that the she said she saw the shooter’s face which she might later have to identify???
The killer wore a mask.... remember?
that he was angry which is pretty much of a given for anyone to do that???
Who was angry?
Her story isn’t that elaborate or that long to be beyond credibility, particularly since it is easily verifiable by the forensic evidence, including the blood on the clothes that she was wearing that day.
Look.... all I want to do is find out is who did the actual killing.
Another early rumor later abandoned.
If he had one on, he could have removed it.
Then again he could have had on a mask with an angry Jason face on it, and that is what she is referring to as him looking "angry".
But I don't see a mask listed as stuff he entered the school with on wikipedia or anywhere else.
So pick your poison. The girl could be right on no matter which way you want to go.
