Damn.. this was the "left over stuff" you were having a hard time moving? I mean.. ASM 9-24 alone is a great run of books and should sell themselves even in mid grade.
Seriously though, at the end of the day, I like others here are just glad you're safe. I agree on safety when dealing with CL transactions as it can be both really good but there is also the possibility of it going sideways like this. Sorry it happened to you but it's good to have reminders like this, for all of us that do frequent Craigslist to be vigilant and have a high level of situational awareness.
I would think the police would be interested not so much in the aspect of comics, even with the high dollar amount associated, but because it was technically armed robbery and there may be repeat occurrences. They were successful once it's likely they'll do it again to someone else.
Like I said though, glad you're safe and I'll keep an eye out for these books up here in the Nor Cal area.
