how to deactivate the record

I have tried several things but using crmservices im getting stuck. In the code below im updating a record, but I also want to set its status to deactivated

                        For Each FMList As new_facilitymanagementprocessinglist In LookupResultSet.BusinessEntities
                            Dim updaterecord As New new_facilitiesmanagement_processing()
                            updaterecord.new_facilitiesmanagement_processingid = New Key()
                            updaterecord.new_facilitiesmanagement_processingid.Value = New Guid(RecordId.Value.ToString)
                            Using sw = New StreamWriter(ImputErrorPath & "importweeklyProcessing.txt", True)
                                sw.WriteLine("2  RECORD FOUND " & FMList.new_facilitymanagementprocessinglistid.Value.ToString)
                            End Using
                            Dim NewLookup As New Lookup()
                            NewLookup.Value = New Guid(FMList.new_facilitymanagementprocessinglistid.Value.ToString)
                            NewLookup.type = EntityName.new_facilitymanagementprocessinglist.ToString
                            updaterecord.new_statementid = NewLookup
                            crmService.Update(updaterecord)
                        Next
                    End If
