I didn‘t realize that this was a sort of companion book to Michelle McNamara‘s I‘LL BE GONE IN THE DARK, which I listened to almost five years ago- but luckily, I remembered that book & the Golden State Killer investigation well. Here Jensen covers his own friendship with the author & involvement as well as the details of his social media process that‘s helped solve crimes through a reliance on geo-targeting & crowdsourcing. A fascinating listen!
