CHIPPEWA FALLS, Wis. — The 14-year-old suspect arrested in the death of 10-year-old Chippewa Falls girl Lily Peters appeared virtually in adult court Wednesday, from a juvenile detention center.

Prosecutors said he fatally strangled, and then sexually assaulted, Peters. 

Judge Benjamin Lane sealed the criminal complaint. Chippewa County District Attorney Wade Newell said after the hearing that three charges were filed against the boy, including first-degree intentional homicide, first-degree sexual assault and first-degree sexual assault of a child under age 13 resulting in great bodily harm.

Chippewa Falls Police Chief Matt Kelm said the suspect is in custody and being held at a juvenile detention center. In a press conference Tuesday evening, Kelm said police arrested the juvenile suspect Tuesday. 

The suspect is a minor who knew Lily Peters; officials would not confirm or deny if the two were related. The family was alerted about the arrest. 

Law enforcement in Chippewa Falls said the missing 10-year-old girl’s body was found near a walking trail Monday morning after she was reported missing Sunday night. She was last seen at her aunt's house, which was blocks away from where she was found. 

Earlier Tuesday, police executed a search warrant at the home of Lily’s aunt. Kelm said the search warrant was for “information tied to the killing.”

The suspect told officials his intent was to rape and kill Peters. He waived his right to be present and in-person at court; all hearings will be conducted virtually. 

The suspect is a 14-year-old male, with the initials C. P. B. His name has not been released.

In a bond hearing Wednesday afternoon, the court ordered $1 million cash bond, as requested by the state. 

The defense argued for $100,000 cash bond, which was denied. 

The court also ordered the suspect to not have contact with juveniles or possess weapons. The court ordered all contact with family members, including his siblings, must be supervised; an adult must be present should he meet with his siblings.

“Protection of community also is necessary in this case given his statements regarding his intentions and his statements regarding that when he did get off the trail, he punched the victim in the stomach, knocked her to the ground, essentially strangled her, hit her with a stick, before strangling her to the point of death — before he then sexually assaulted her,” Newell told the judge at the bond hearing.

The judge set a May 5 status hearing in the case.

Kelm said he does not believe there is an active danger to the community. 

An autopsy is currently being conducted on Peters in Ramsey County in Minnesota. The results were not yet released, but will be given to the Chippewa County medical examiner when they're complete. 

Kelm said the department has received more than 200 tips that were "critical" to solving the case. 

“While nothing will bring Lily Peters back or change what happened, we are very grateful to be able to deliver this news for the family and for the community,” Kelm said.

The investigation reportedly is still active; tips may be submitted to the police non-emergency tip line. The previously dedicated tipline has been closed at this time.
