THis is from Ann Rule´s files. It says there were no clothes.
"When 5-year-old Heidi Peterson vanished in a matter of a few minutes from the sidewalk in front of her house in February 1974, Seattle's heart broke. No child could disappear so fast, but Heidi had. Police and volunteers combed the neighborhood. I remember riding all night with a K9 unit, hoping desperately that the German shepherd accompanying us would help us find her.
But we couldn't find Heidi along her tree-lined block of comfortable Dutch Colonial homes with children's tricycles and bikes on their porches. I remember that it was raining hard and the thought of one little girl lost somewhere close to us was frightening.
There were rumors and tips. Someone said they had heard a child screaming in a house one street over. But when detectives investigated, there was no indication that Heidi had ever been there.
It was the next winter when the snows came before anyone knew where Heidi was. On the corner a half block south of her house there was a vacant lot where wild blackberries had towered eight feet or more over the ground for years. But this snow was heavy enough to make the vines break and flatten to the earth. Heidi's skull was there, and the fractures in it showed the cause of her death--bludgeoning with some heavy object. There was no other evidence left. No clothes. No weapon. Nothing at all that the killer might have left behind.
The homicide investigators continued to check residents in an ever-widening circle with Heidi's house in the center. They found men with records for sexual crimes and younger men whose answers to their questions didn't
quite add up. They had a suspect in mind, but they could never link him to Heidi's murder.
One of the things detectives count on is that even the most secretive murderer usually has to tell someone, either to brag about what he has done or because he feels guilty and is compelled to talk. Allegedly, Heidi Peterson's killer told the woman in his life, and when they broke up, she told someone else. Eventually, word reached Seattle detectives. They were sure they knew the killer's name.
They looked beneath a house where the suspect said he had left evidence, but too much time had passed. It was gone. They could not arrest him.
Heidi's case is a classic example of a case closed "Exceptional." But someday the person who killed her will pay for the horrendous crime against her. One way or the other."
