It was a warm September afternoon in 1985 when 16-year-old Kimberly “Kim” Simon left her home in Marcy, New York. She was headed out for a walk—planning to meet a friend at Whitesboro Junior High School. It was supposed to be a simple, familiar route along Mohawk Street.

But Kim never made it.

The next day, her body was discovered in a wooded area less than a mile from her home. She had been murdered. And in an instant, a quiet community was forever changed.

In the decades since, Kim’s case has been marked by confusion, controversy, and painful missteps. Investigators chased countless tips, wild theories—even rumors of cult activity. A man was ultimately arrested, convicted, and sentenced to 25 years to life for her murder. But nearly two decades later, that conviction was overturned—thanks to DNA evidence and the work of the Innocence Project.

For 20 years, Kim’s family believed justice had been served. Then, it was ripped away.

Now, as the 30-year anniversary of Kim’s death approaches, her loved ones are still searching for answers. And they’re not alone.

Investigators are once again asking the public for help. Maybe you heard something. Maybe you know something. Maybe, after all this time, you’re finally ready to speak.

Kim Simon deserves the truth. And her family deserves peace.

If you have any information about Kim’s murder—even something that seems small—please contact the Oneida County District Attorney’s Office at (315) 798-5575 or Crime Stoppers at (866) 313-8477.

This is The Lost Girls—and this is the story of Kimberly Simon.
