claim removal

hi, sorry for asking for the same thing again, i found another claim of a player who hasnt joined the server in sometime. is it possible to remove that claim also because its next to my claim and i cant claim the entire land because of it. 

here are the coords - X: -8502.434
                                 Y: 65.00000
                                 Z: -9934

thank you.
