I can’t wait till the release date of Sheryl’s book. May 12/26. I really hope its being released in Canada🙏 I love listening to Zone Seven, it is so insightful. One of my favourite pod cast.
Found you through TCG, and absolutely love you!! Binging all your episodes. I’m so glad there are people like you searching for the missing and keeping cold cases alive! A coworker mentioned his hometown (Clinton, Mo) has a missing woman, Angela Hammond, and I’d love to know what you think of that case. Also love to hear you cover a “local to me” case on Mischelle Lawless (Benton, Mo).
I love this podcast I just found through the host’s appearance on TCG! Her voice reminds me so much of Kathy Bates as Jo Bennett on The Office!
Sheryl, I absolutely love the show. You are so kind, down to earth, and capable. Whenever I hear your voice I envision Reba McEntire circa 1990 Tremors. 💕
