Get OmniDisk Sweeper (free) to see where all the space is being used. Don't start deleting things, just yet.
However, it won't show you the disk usage of other users. For that, you will have to log in to their accounts.
There are some other things we can look at if you can't locate where the disk space is going, using the above. (Could be a "ghost" volume from a failed backup or some runaway error logging. But first check using OmniDisk and the space being used by other users, if any.)
