How does Harold Schechter use imagery in Deviant: The Shocking True Story of Ed Gein, the Original Psycho?

Examples of Imagery:

"As he recalled years later, Eddie 'rolled his eyes and wiggled his nose like a dog sniffing a skunk.' Then he smiled and said, 'She's not missing. She's down at the house now.'" Chapter 9, Page 53

"For the dozens of local lawmen involved, the investigation of Bernice Worden's murder had turned into a macabre form of excavation. Sifting through the rubble of Gein's house was like conducting an archeological dig in hell." Chapter 14, Page 80
