SUIM can't say that who deleted that table and which time.
Generally, the table T16FK doesn't store the manual changes as in standard the Logs Changes Data is not ticked in SE11 - Technical Settings
If the user deleted that entry from table edit (SE16N - &SAP_EDIT), then you can't able to see the changes.
If the table has been changed by some program or IMG configuration, then you may can see that from t-code AUT10.
But T16FK is for release status, there are no IMG configuration to delete a line item from this table.
