Rosco’s was a dark bar, smoky, lots of taxidermy on the walls, and the first place where Danielle Trussoni heard her father, Jim Trussoni’s war stories. Jim was a Vietnam vet, drafted from Wisconsin at the outset of the war, and immediately volunteered to be a “tunnel rat,” and plumb the labyrinthine and oftentimes booby-trapped Viet Cong tunnel systems. Jim now suffers from Post-Traumatic Stress Disorder and Danielle attributes it primarily to his time underground. This past year, Danielle went so far as to write a memoir, entitled Falling Through the Earth, which describes what it was like growing up beneath this man and how his PTSD effected her life as well.

Danielle sat down with NPR’s Weekend Edition to discuss the book. She begins as a 5 year old who just recently found dozens of photographs of Asian men in her basement, which she would later discover were of Viet Cong Jim had killed. “He really cherished them,” she says. This was her first encounter with her father’s PTSD, though they did not speak about the photos until 14 years later, when Danielle was doing a project for a history class at U. of Wisconsin. She interviewed Jim about his experience, and quickly realized that the stories she’d heard as a child had changed, sometimes for the better, other times not. “They were fraught, very emotional,” she says of the interviews. “Jim never felt remorse in the way I wanted him to feel remorse for those deaths, and I guess a solider can’t.”

In researching the memoir, Danielle actually went to Vietnam and retraced her father’s foot steps, even plunging down into preserved Viet Cong cave systems in hopes of understanding better Jim’s mindset. “It did [help me to understand. I could feel the heat, and I could feel the claustrophobia, and I could see nothing ahead but…nothingness”.
