Briggs Softworks

I am currently single table tourneys with my co-workers.
My Dilemma:
There is a player that has WON 10 tourneys in a row. Now I know some players can and are better than other but is there a possibility that he is cheating somehow??? I mean...just the way he plays kinda brought up a Red Flag. I mean I live around Poker, We all are Poker Dealers and I myself am a Poker Room Manager. Is it possible this guy is running a utility, (bot) or something helping him out???

Can someone please give me some advice on this...Any input would help!

Thanks...

If it is YOUR site, can't you look at the hand histories and see if somebody is chipdumping or collaboratating, or anything else suspicious?
