In the event it seems unlikely that the hinge bolts would simply 'go
missing' (and really--- they're not going to fall out by
themselves), I'll also point out that the right latch plate is
installed backwards. Someone messed with this case at some point
and did a half-assed job of it. It doesn't seem the least bit
unlikely to me that someone who'd install the latch plate backwards
and not notice [the latch doesn't work at all if the plate is
backwards] would also forget to put the hinge bolts back in.
