(KARE) Wisconsin prosecutors say the driver of a pickup truck that struck and killed three Girl Scouts and one of their mothers Saturday was intoxicated after huffing aerosol chemicals.
The driver, 21-year-old Colton Treu, took part in a video hearing to set his bond at $250,000 Monday morning.
Prosecutors expect the official criminal complaint to be filed by Tuesday, when Treu is set to make another court appearance. Among the charges will likely be four counts of criminal vehicular homicide.
The fourth-graders and a mother were collecting trash in Lake Hallie Saturday morning when they were struck by the truck. Investigators say Treu, sped away, but a sheriff’s investigator was able to track dripping vehicle fluids nearly two miles to an address in the city of Chippewa Falls.
