Saturday marks 45 years since the murders at Gitchie Manitou State Preserve.
Many people in KELOLAND have read the book that details what happened that November night.
A husband and wife released it in early 2016.
The first book, “Gitchie Girl” tells the story of five teenagers who were spending an evening around the campfire.
They were attacked by three brothers.
Four boys were shot and killed.
A fifth teen, Sandra Cheskey was raped.
She just started talking about that horrific night in recent years.
When Phil and Sandy Hamman released the book “Gitchie Girl,” a new chapter opened up in Sandra Cheskey’s life.
“All of a sudden I wasn’t walking with my head down anymore, which I had been taught to do. ‘Walk with your head down. Then the reporters can’t get any pictures,'” Gitchie Manitou Attack Surivor Sandra Cheskey said.
One of the authors, Phil, was a good friend of Mike Hadrath, one of the boys who died.
“She knew that I had a personal connection so she trusted that we would do the right job on the book,” Co-Author Phil Hamman said.
Now, the Sioux City-based authors are working on a second book: “Gitchie Girl Uncovered.”
The book shifts the focus to the three Fryer brothers, the men who are now spending life behind bars for the crimes.
“There’s some strange and bizarre twists to the investigation. That will be in the second book. A lot of things we didn’t tell in the first book,” Phil Hamman said.
“People also want to know what makes people tick. What would make three brothers do something so horrific?” Co-Author Sandy Hamman said.
“Gitchie Girl Uncovered” will be released on January 8.
The new book will be available immediately on Amazon.
It will be sold at various locations in Sioux Falls a few weeks later.
