Plot summary
In August 1991, South Portland, Maine resident Pearl A. Bruns is missing after an argument with her husband William “Bill” Bruns. Despite pleas from her children, police insist on treating it as a routine missing person's case.

But when an investigation turns up a blood trail that leads to the couple's basement, police are sure that they'll find the victim's body. Initially, they find nothing and the case stalls, until new forensic technology helps investigators find the body.

The investigators first use luminal over the cleaned carpet to reveal the blood spatter on the floor and a path down to the basement. Then, they use ground penetrating radar to scan the basement for radiation; they found three feet down, excavated rusted sand everywhere except in a certain area. The body had absorbed the rust and was found there.
