It looks like there is a cover plate on front of the deadbolt from the picture,
I could be wrong though. Check both sides and see if you can pry up the
cover plate, if there is one, using a screwdriver. If so, you should be able
to see the screws then. Just a guess.
Not an expert, but I have changed out a lot of locks around my house.
If you see posts connecting the two sides, this should be where your screws
line up on the front or back. Worst case, if you have a drill with metal bits,
just make a guess and drill from the front or back around where posts are, and the lock should fall off.
