The 21-year-old driver who allegedly killed three Wisconsin Girl Scouts and one of their mothers over the weekend has reportedly admitted to inhaling chemicals prior to the crash.
The youngster, who can not be identified because of her age, appeared before Chippewa County Circuit Court on Monday - an adult court - because of the severity of the allegation.
Officials said she had been removed from the home of her biologial parents and was placed in a foster home. Another 10-year-old, identified by her mother's Facebook account as Madalyn Zwiefelhofer, remains hospitalized in stable condition.
A 10-year-old girl has appeared in court in Wisconsin charged with killing a six-month-old boy.
Treu initially fled the scene but later turned himself in and is now facing initial charges of four counts of homicide by negligent operation of a vehicle, four counts of homicide by intoxicated use of a vehicle, four counts of hit and run involving death and one count of hit and run involving great bodily harm, according to information provided to Oxygen.com by the Chippewa County Sheriff's Office.
Judy Schneider, the mother of Sara Jo Schneider and Haylee's grandmother, told The Associated Press in an interview Monday that after the crash she wondered, "What was the driver thinking?" Police say he and his passenger, who is also in custody, said they'd been "huffing" or inhaling vapors from an aerosol cleaner before the crash, something prosecutors had argued in court. A fourth girl scout, who has not been identified, was hospitalized and is now in stable condition, police said.
Treu remains at the county jail on $250,000 bail, reports CBS News correspondent DeMarco Morgan.
The children were all fourth graders at Halmstad Elementary School and Southview Elementary School in nearby Chippewa Falls, about 145 kilometres east of Minneapolis.
The victims were among seven children and five adults who were working in the ditches along the roadway.
The local Girl Scout group consisted of 12 persons (5 adults and 7 children) who participating in a highway cleanup project.
The victims were picking up trash in the ditches of County Highway P when they were struck Saturday about 11:30 a.m. Police have arrested 21-year-old Colten Treu, of Chippewa Falls.
The Chippewa Falls Area Unified School District says it's received a lot of support from the community and even from around the country.
