Any idea who he was working with in that space?
Hard to say. At least, their name doesn't appear to be on the building, and a search of the actual address didn't turn up any names newer than 2012 (except maybe a "Steven Manthey?"). Business listings all say it's a 2-person company, but everywhere I find a listing it's always Kurtz, Kurtz, Kurtz, with no mention of who the other person might be (though they helpfully give Kurtz's phone number if you want to call and ask). He's only been there since 2016, and his lease was only going to run one more year.
The dispensary could trim back those trees, they overhang the entrance and look like they'd hide a lot of mischief.
This all happened less than a week ago, so I'd say he was rather motivated.
