There are three ways to mark a person as deceased.
Go the user profile of the person you want to mark as deceased. In the actions pane in the sidevar, click ‘Mark as Deceased’.
Select the person by clicking the box that corresponds to their name and then scroll down to ‘Mass Manage’.
In the ‘Choose Action’ dropdown, select Change People’s Field > Deceased > Yes, and click on ‘Perform Mass Manage’.
You can create a CSV file listing deceased people which can then be imported. Create a column for Deceased and add a ‘Yes’ against the person you wish to be Marked as Deceased. Check out this Import People file for more information.
