The game cuts off after that anyways, for all we know Jessica is dead in the corner of a room, having tripped face first on a pointy table.
Seriously, lets say Eva was actually a murderer in this case, do you think Jessica could have hidden somewhere that Eva couldn't reach?
It couldnt have been far, it was a few steps from what I remember. If it was far enough to elude her then chances are Eva would return to see George's fat ass not crushing Shannon and would certainly find it suspicious.
