Shiverdecker disappeared Dec. 9, 1994, after basketball practice. She was supposed to call her brother Christopher Shiverdecker, then 16 years old, to pick her up, but she never did.

Alabama state troopers received an anonymous call on Feb. 25 of the following year pointing them to a body in Coosa County. Authorities found her remains in a wooded area near Highways 9 and 22.

The 15-year-old was a student at Benjamin Russell High School in Alexander City, Alabama. One of her schoolbooks and her purse were also found near her body. Due to the state of the body, authorities could not determine the cause of death.

In a 2019 report by the Alexander City Outlook, Shiverdecker’s mother Gloria Idiaan said she had a copy of the autopsy report and it said investigators never found other DNA at the crime scene. She added that after the remains had sat out for over two months, “animals had gotten to her,” which made determining what happened much harder.

Idiaan also told the local newspaper she had suspects, but one has died and the other left Alabama. She described her daughter as a “social butterfly” who sometimes struggled to fit in due to her albinism and being legally blind.

She said despite Shriverdecker knowing she would be a benchwarmer, she was very happy to be a part of the basketball team.

“Our thoughts and prayers continue to go out to the Shiverdecker family,’’ lead investigator Alexander City Detective Drew Machen said. “We are dedicated to bringing closure and justice to your family.”

Christopher Shiverdecker marked the 27th anniversary of his sister’s disappearance with a Facebook post on Dec. 9.

“27 years is a long time to spend countless days considering the same unanswered questions. To be lost in a terrible limbo of suspicion and wonder. To know that there is an answer out there but to remain elusive to this day. It’s been 27 years to the day that my sister went missing and the case is still unsolved,” he wrote.

But he said he remains optimistic “that answers may be possible.”

“The internet and Facebook have been invaluable tools in spreading awareness of this case. … It is, as it always has been, my hope that the right person does the right thing and come forward with the answers to allow this case to finally be closed,” he said.

The post asks that anyone with information about his sister’s disappearance please contact the Coosa County Sheriff’s Office, or Machen at 256-329-6746 or Crime Stoppers at 334-215-STOP.
