On the night of June 5, 2019, an 18-year-old named Nikki Kuhnhausen left her apartment in Vancouver, Washington, and was never seen alive again. Her remains were discovered months later on Larch Mountain, and she had been strangled to death. The last person known to have been with her was a man named David Bogdanov, who gave a long, rambling interview to detectives in October 2019. That interview—and the investigation that followed—reveals how a chance encounter, a violent reaction, and a family's silence converged into a homicide case.

David Bogdanov told detectives that he first met Nikki in the early morning hours of June 6, 2019, while he was heading out to a bar with his brothers. He said he saw her walking alone in downtown Vancouver, offered her his jacket and some vodka, and exchanged Snapchat information. Later that morning, after the bars had closed, Nikki contacted him. According to David, she asked for a ride to retrieve her phone, which she said was in Beaverton. He picked her up in his brother's white work van, and they drove to his parents' property in Brush Prairie to switch vehicles so his brother could go to work.
