LAKE HALLIE, Wis. – Clad in bright lime-green safety vests, two small groups of Girl Scouts and their adult companions walked along both sides of County Road P in western Wisconsin's Chippewa County late Saturday morning, chattering and laughing as they picked up litter.
The fourth-graders had adopted that rural road and performed the community service along it before, clearing the stretch that runs through farmland and residential areas just northwest of Lake Hallie in the spring and fall.
Suddenly, a black pickup speeding by veered off the road into the shallow ditch where some of the girls were walking, striking several children and a woman accompanying them. The truck then lurched back onto the road and sped away, according to police and witnesses.
Left behind was a scene of horror — two girls and the chaperone lay dead by the roadside. Two other Girl Scouts were taken by ambulance and helicopter to a hospital, where one died later Saturday.
The surviving girl remained hospitalized in Rochester late Saturday in critical condition.
The driver of the pickup that hit them, 21-year-old Colten Treu of Chippewa Falls, later surrendered himself, according to Sgt. Daniel Sokup of the Lake Hallie Police Department.
Treu was being held at the Chippewa County jail, where he is expected to be charged with four counts of homicide through the negligent use of a vehicle, Sokup said.
Authorities say the crash occurred before a hill and there were no blind spots. It's unclear whether Treu was somehow distracted at the time, he said.
