One night in 2020, a woman named Beth Van Oss paced back and forth in a small room in the house she shared with her boyfriend, Mike, in rural Colorado. She dialed Mike’s phone number again, and put her phone to her ear. But just like the last time she’d called – he didn’t answer. Now, Beth was afraid. He had left that morning, headed for the woods, promising her that when he came back – they would finally have everything they had ever dreamed of. And he had taken something with him. Something that he had become obsessed with. Something that Beth had begged him to forget about, and throw away. But he had refused. And now, he was gone. Beth dialed the phone again, but this time, she called the police.
