It's interesting to see so many people convinced it's related to their specific media they saw (all unique from each other). I think this is more indicative that the issue is just well known and this is a response to the issue at large rather than a specific instance.
Having freshly heard the NY Times piece on a recent teen suicide stemming from ChatGPT, I don't think it's wrong to assume that it's playing a large role here as what ChatGPT did in this instance was egregious. Feel free to judge for yourself.
We have existing precedent that encouraging someone to kill themselves can result in you being criminally responsible. Is software doing its best to be human that different?
