I wanted to recommend a really interesting presenter named Tobin Buhk. He's a historical true crime writer we hosted virtually last evening for a fantastically interesting event called The Lonely Hearts Killers. We had him in person a couple years ago for another event, and he really is an interesting speaker. He's thorough, funny, and extremely knowledgeable in his topic areas.  

Here is his email contact: Tobin@tobinbuhk.com
