[Mobile][Mid 2000s?] Old Detective Mystery Game

I remember playing this super old detective game on my parent's flip phone. I don't remember much details but here is what I do think off when I think of this game:

- I remember some sort of a casino level/scene with some exposition

- I remember a prominent feature in this game is a handwriting matching minigame where I try to see if a piece of evidence with handwriting matches with a suspects handwriting

- I remember lots of dialogue, I guess its more of a storytelling game with not a lot of movement.

- I'm not sure if I'm making this up or not but there was some violent parts (like suicide even?) and crazy plot twists.

Thank you!
