I hope y'all get your stuff eventually and Jeff is OK. There must be some reason(s) why he disappeared, but I don't think it's helpful to speculate about it. The statute of limitations may be close to expiring or already has expired for any criminal action. If you contact a lawyer, and I'm not encouraging that, but maybe you can get good legal advice for civil court. The money is of course only part of the value - the time, energy, etc. spent, but maybe you could at least recoup the money for the posters that Jeff has or had.
