This is terrible. I met Ian when we worked at the same company for a bit, and he was a great man by my interactions with him. Just heartbreaking to read.
He went on a tirade the other night on Twitter after what he reported was a run-in with the police. The tweets got more incoherent as the evening went on, but it read like he was backing down from suicide. Since the linked release doesn't say that and it looks like he closed his Twitter, I guess we don't really know what went down. He also doesn't seem to have published the promised blog post. What a shame. I wish he'd found the help he was looking for.
