The Wisconsin Department of Criminal Investigation and the Wisconsin State Crime Lab have joined the investigation into the death of 10-year-old Lily Peters in Chippewa Falls. Police Chief Matthew Kelm says no arrests have been made but investigators are following up on multiple leads. The girl had ridden her bicycle to her aunt’s house Sunday night but never returned home. Searchers found her body at about 9:00 a-m Monday. The cause of death hasn’t been released. Helm says several law enforcement agencies are working around the clock to solve the case.
