In Part 4 they put Jason in the ice box with the rest of the dead people... then we see his breath in the cold air...
Why would he be put in there if he were alive? Wouldn't the doctors do more to see if he were dead then just by the fact that he's not moving?
Didn't they check his pulse or anything? Heart... breathing... nothing?
So remember in The Final Chapter when Rob has the picture from the paper? The same one Tommy later uses as a guideline to shave his head and such. When he shows it to Trish I believe he says it was an "artists rendition of Jason as a child from a would be victims description", Or something along those lines? Where would they possibly get this description, and from whom? Why would it be put in the newspaper?
The only person I can think of that would give a description of seeing young Jason would be Alice. Why would they take her description when they didn't believe her in the first place, and then call in a sketch artist to have it put in the paper.
Any takers on this perplexing mystery?
