A major development has brought new clarity to the tragic death of 10-year-old Lily Peters in Chippewa Falls, Wisconsin. On August 26, 2026, her cousin Carson Peters-Berger, now 18, pleaded guilty to first-degree intentional homicide and was sentenced to life in prison, with eligibility for extended supervision after 25 years.

During the proceedings, the judge specifically confirmed with Peters-Berger that by pleading guilty, he was admitting that he killed Lily and planned to do so. Investigators had previously reported that he told them he intended to attack Lily “from the get-go” after following her along the trail as she rode home from her aunt’s house.

Lily disappeared on April 24, 2022, after leaving her aunt’s home. Her father reported her missing that evening, and her body was discovered the following morning in a wooded area near the walking trail. The case immediately triggered a massive search and devastated the Chippewa Falls community.

The latest court development also means the case will not go to the previously scheduled trial. Under the plea agreement, two additional sexual-assault charges were dismissed but read into the record, allowing the judge to consider the allegations when determining the sentence. Peters-Berger also received credit for roughly four years already served and was ordered to pay more than $30,000 in restitution.

Meanwhile, the memorials shown in the image — filled with flowers, teddy bears, balloons and handwritten messages — remain a powerful reminder of how deeply Lily’s death affected the community. Purple decorations became especially prominent because it was reportedly her favorite color.

What makes the latest update especially disturbing is not the discovery of a single new physical object, but the new legal confirmation of what investigators had been alleging for years: the killing was intentional and planned. The guilty plea has now transformed those allegations into an admission supporting the homicide conviction.
