Over 42 years have passed since the unresolved death of Kellie Jean Poppleton, but the Alameda County Sheriff's Office has not given up on seeking justice. In a recent social media post, authorities reiterated their call for witnesses or anyone with information to step forward. Kellie, only 14 at the time, was found deceased on December 2, 1983, alongside Kilkare Road in Sunol, and was identified as a student at Conrad Noll School in Fremont.
Details of the fateful day are sparse but significant. The last time Kellie was seen alive was on the corner of Darwin Drive and Fremont Boulevard. Noticing something suspicious, witnesses reported a Black Pontiac Trans Am near the crime scene. Struggling for leads, investigators are urging public cooperation. They've asked anyone with information to contact the Cold Case Homicide Unit directly at (510) 667-3661, or to leave an anonymous tip at (510) 667-3622, emphasizing that even the smallest detail could be crucial.
The Alameda County Sheriff's Office, renewing their plea for help, demonstrates their commitment to unearthing the truth behind Kellie's death. Through their X post, shared yesterday, they hope to re-engage a community that may hold the key to solving this longstanding mystery.
