Rangin hears the news from the computer and scratches his head. Nothing matches and there isn't anywhere really left to search. Well, the only other place to search who could possibly have been around were the ships in orbit, but that would involve someone getting up and down from them...well there had been that teleport signal. Oh why not...last one really. After this, he would have to ask the others from some ideas.
"Computer, access available crew rosters for all ships in orbit, find crew fingerprints and compare to partial fingerprints for match." Rangin eyes roll up to the ceiling, "Good Luck" he whispers.
He sits back and idly drums his fingers on the worktop waiting for the likely response of no matches and for Officer Peters to return.
