My latest. I heard about this growing up and spent the last few years seeing what FOIAs, interviews, and archives can tell us. It’s a glimpse into the murky, ruthless underworld of 1970s Texas. Grateful for my brilliant editors @gycsak.bsky.social @liseolsen.bsky.social @beaudonelly.bsky.social

Tomorrow in De Telegraaf one of the craziest international art thefts I have ever solved. A story about a fantastic painting and a murder. A story worthy of a Spy novel.

New from me!
This article dives into a sketchy non-profit (so they claim) that Clothoff is supposedly donating money to.

Lots of dodging of questions, and no evidence to suggest that they exist beyond a website.

@koltai.bsky.social delves deeper into Clothoff. The app notorious for generating non-consensual deepfake pornography now claims it is funding an organisation to support those affected by AI. The ownership of this organisation, or how it helps victims, is unclear. www.bellingcat.com/news/2025/02...
