Yes, Kirsch seems to generally do a decent job vetting and organizing info on his substack (https://stevekirsch.substack.com/) and there are some reliable sources with long video interviews, but finding good, boiled down, sources to share can be a challenge.
Interesting context on the suitcase murder, thanks.
It has been mentioned in Ukraine threads... As of today, it is still being used as clickbait all over the place. eg.

In that one they actually do mention that “The 23-year-old killer slept with Vedler’s corpse in a hotel for three days while posting on her social media to not alarm people of her disappearance.” But they forget to mention that he was her boyfriend and not a killer sent by Putin. At least the Post had the decency to say, “Vedler’s ex-boyfriend Dmitry Korovin, 23, has now confessed to strangling her to death".
