WPF with datagrid to delete selected items

I have a Datagrid that get filled from a SQLite table

Connect();
mAdapter = new SQLiteDataAdapter("SELECT * FROM clients", mConn);
mTable = new DataTable();
mAdapter.Fill(mTable);
dataGrid.ItemsSource = mTable.DefaultView;
mConn.Close();

I can make it delete an selecteditem but how can I make it delete selecteditems based on their id

private void dataGrid_PreviewKeyDown(object sender, System.Windows.Input.KeyEventArgs e)
    {
        if (e.Key == System.Windows.Input.Key.Delete)
        {
            if (dataGrid.SelectedItem == null)
                return;
            DataRowView rowView = (DataRowView)dataGrid.SelectedItem;
            Connect();
            using (SQLiteCommand mCmd = new SQLiteCommand("DELETE FROM clients WHERE ID=" + rowView["ID"], mConn))
            {
                mCmd.ExecuteNonQuery();
            }
            mAdapter.Update(mTable);
            mConn.Close();
        }
    }
