Killing of Lily Peters

On April 24, 2022, Liliana Marie "Lily" Peters, a 10-year old American girl, was killed and raped in Chippewa Falls, Wisconsin. The killing gained significant attention and media coverage due to the ages of both the victim and the suspect.

On April 26, 2022, Peters' cousin, 14-year old CPB was arrested on charges of murder and rape. The accused, Carson Peters-Berger, was originally publicly identified only by his initials "CPB". He may be tried as an adult due to the murder charge.

Murder
According to the criminal complaint, 14-year-old Carson Peters-Berger asked his cousin, 10-year old Lily Peters to take a walk and explore a trail. Lily took her bike and Carson took his hoverboard. Once they were off the trail, it is alleged that Carson punched Lily in the stomach and pushed her to the ground, then hit her in the head three times with a large stick and strangled her until she was dead. Carson then allegedly raped Lily's dead body.

The criminal complaint alleged that Carson then became scared and fled, went home where he showered and cleaned his clothes, then went back to the scene and dragged Lily's body a few feet and covered her body with leaves.

Investigation
Liliana Peters was reported missing by her father and her body was discovered the following day at 8:54am. Two days after Lily's killing, Carson Peters-Berger, Lily's 14-year old cousin, was arrested and charged with the murder and rape of Lily. According to authorities, Carson confessed to killing Lily and that it was his plan the entire time to kill and rape her. He may be tried as an adult, though his defense team is trying to keep the case in juvenile court. Carson's bail was set at $1 million. If convicted, he would face a sentence of life in prison.

Carson's father, Adam Berger, had served 3 years in jail for possession of child pornography.

In January 2024, it was determined that Carson would be tried as an adult. In February 2024, prosecutors said they were aiming for a trial date in April 2025.
