Help? SourceTV demo and Steam ID

[Bane of Soldiers]

The demo should have the sb_status output in it and that should tell you the players steam id.

Also when exactly was this?

It was right after a server restart (the server was restarted after a glitch allowing the humans to shoot each other "pub style" occurred). I didn't see him in server before the restart. I'm not very adept with console or demos, so I'm not sure how to manipulate sb_status; it would only display the players' steam IDs at the start or end of a round. Again, the player joined before the round started and left before it ended. This was yesterday, May 08, at 6:10ish to 6:15ish PM on the map ze_voodooislands_v7

Edit: was that steam id/IP info even available through sb_status?
