Okay, So, I've heard there are multiple endings to the game.. and it all goes on what decisions you make throughout the game.. Well I've just completed it.. and my ending was...

(WARNING:SPOILER COMING UP)
The killer is Scott Shelby, and it ended with Madison Paige entering Shelby's apartment, and finding behind the wardrobe that Scott Shelby was actually a killer (she found out from visiting his real mum in hospital) and then he locked her in, and she managed to escape but the building was on fire, and when she got out it exploded, anyway I chose the option to call Ethan, and he was like.. yeah, thanks. Then it took me to the warehouse where he is confronted by Scott Shelby, and he explains he was trying to find a father worthy of sacrificing himself as opposed to letting his son die.. and Madison pulls up but Blake is determined to prove Ethan is the 'Oragami Killer' anyway, Shelby falls into the compactor thing after fighting with Jayden, and Madison has gone in to see Ethan, and explain the cops have the warehouse surrounded.. so yeah, they all decide to go out, and he's let free. Then it cut to a news broadcast saying they found Shaun Mars and Shelby was the killer. Then it cut to a talk show, with Jayden being crowned the hero for single-handedly ending the murders of the Oragami Killer. Then it cut to Jayden in the toilets flushing a vail of Triptocaine down the toilet. Then it cut to Madison, Shaun & Ethan in an attic, basically showing they're a family now, and that will be there home etc. Then it cut to Shelby's grave saying Feb '67 - Oct '11.

It seemed to me like ALL the endings were shown in a sequence.
Is there alternate endings still? If so, can you describe them, thanks. :']
