Is there a way to track who/when deleted a line item in a Sales Order?

We are having an issue where line items are being deleted from active sales orders either manually or via our pick/allocation process.  We can see these deleted line items in Sales Order History, but is there a table with history as to when/who deleted them?

I know you can right click the inquiry page to see who last touched the sales order (System Information), but this shows the user that invoiced against it and he/she did not delete the line item.
