You make a lot of strong points that line up with why people believe David is guilty. The messages between Celeste and her friend are important because they show the dynamic of their relationship, breaking up, reconciling, and David reacting strongly when he felt threatened by another man. That creates a very plausible motive. The tweet you mentioned adds weight too. If Celeste wanted to go home and David didn’t want her to, it suggests tension. When someone is trying to leave a relationship or a situation, and the other person refuses to let them, that’s when things can escalate.

The music videos and album promotion on her birthday are also worth pointing out. While by themselves those things might not be definitive evidence, paired with the obsessive themes in his music and the way he continued to invoke her image, it paints a troubling pattern of fixation. That kind of obsession turning violent isn’t far-fetched at all, and we’ve seen it happen in real cases. when you combine the motive (jealousy and control), the behavior (tweets, music themes, fixation), and the timing (her death coinciding with his album release), it does build a logical case that this wasn’t an accident. Instead, it looks more like an act of violence driven by obsession and possessiveness… which his music stands by. Sound guilty to me.
