The early version was following this somewhat; Curtis kills Dan, Garcian finds his body. The differences being it's not on a basketball court and it probably isn't 1975. There was a a coherent story at one point.
Damn I wish that was the game that we got.
Look here, It's Dan Smith & Sundance Shot.

Man, I wonder how the hell Suda was planning to explain that one.
(Sundance gets arrested at the end of "Flower Sun & Rain".)
Although that Dan Smith scene most likely occurred during the 70's, 60's back when Sundance was still a politician.
I remember reading a Japanese site that went on & on about how the
"mysterious guy" looked cooler than Dan Smith.
Mysterious guy refers to Sundance. Although at this website, "mysterious guy" refers to the Jaco/Kosaka guy that Dcat posted.

Or at least it will. Once I get around to posting up a speculatory page about this unknown guy.
Too bad nobody knows the real reason that Sundance was cut from the game.
I'm guessing it's because Sundance was one of the more integral characters from FSR & the Silver Case games.
We wouldn't know what's so significant about him, because FSR & the SC games have never been ported over.
(He only appeared in FSR, but he has so much influence that a lot of events in the earlier Suda games are direct after effects of what Sundance's assassin did during the night of the Silver Case murders.)
I remember when I beat FSR, I had no idea what was so special about the Tetsuguro guy until after I played SC.
It's this interconnectivity of Suda's games that attracts me to his unique surrealist setting.
Too bad it seemed to stop with SC 25 Ward.
