How can we see who/if someone has created a database connection in FRS?

Summary: We have noticed an extraneous database connection in FRS that is not one of the ones we have created ourselves in our production environment. Is there a way to see who has created this? As far as we can tell, no reports are using this connection. Our fear is that this was sitting in the instance prior to go-live - and the prod instance was not properly cleared. If we can confirm that someone internally created the connection, then our worry would be ameliorated.
