CHIPPEWA FALLS, Wis. — Law enforcement in Wisconsin have launched a homicide investigation after discovering the body of a 10-year-old girl near a walking trail Monday.

Police arrested a juvenile suspect that knew Iliana Peters, who went by the name Lily, they announced Tuesday evening. 

During a Tuesday news conference, Chippewa Falls Police Chief Matthew Kelm didn’t provide the age or sex of the suspect, whether the suspect was related to Lily or where the arrest occurred. He said there was no longer any danger to the public.

“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.

Iliana Peters was reported missing Sunday evening. She was a fourth-grader at Parkview Elementary School in Chippewa Falls. Here is what we know about the situation:

Police arrested a juvenile suspect Tuesday

At a press conference Tuesday, Kelm announced that a juvenile suspect was arrested earlier that evening. He said the suspect was known to Lily.

But he declined to provide any further information, including the suspect’s age or where they were arrested. 

Kelm said he no longer believed there was a danger to the public, indicating he believes the suspect acted alone.

Kelm did say that officers executed a search warrant on an address along the same block where Lily’s aunt lives. But Kelm did not say whether that search yielded anything of value.

Was an Amber Alert issued?

Police did not issue an Amber Alert after learning Lily was missing. In a news release before her body was found, police said the situation did not meet the criteria for an alert, but did not elaborate further.
