Not sure about Patrick. Casey acted like she didn't recognize him but in another thread it was revealed (weeks ago) that he worked for a news outlet (Sentinel? I can't remember) and perhaps they sent him to try to get a scoop or something. I think this is his MySpace page:

No idea about Waters.
Kostakis - apparently a friend/drinking buddy. An interesting side note is that she gave a big statement regarding the death of Jesse Ortiz - the guy many suspected of being Caylee's father. You can read her comments at the obituary here:

Downing is a party bud of Casey's. She is in many (most) of the photos posted of Casey partying - prior to Casey meeting Mr. Lazarro. She was in the photos of Casey "tonguing" the Taco Bell dinner and also the photos of Casey's 21st birthday - where she's got her head in some public toilet. (Eeewww.)
I also found this link to help you with other players and their Myspace pages:

Maybe others have more info or you can look on the "Players" link here on WS.
