Treu and his passenger, who was not identified, turned themselves in to authorities Saturday afternoon. Authorities said both said in statements to police that they had been huffing before the crash.
“Words cannot describe our Lake Hallie community’s sorrow for the witnesses, victims, and their families,” Smokowicz said. “This is a horrible reminder of our (nation’s) epidemic of self-indulging with substance abuse without regard of the consequences.”
Authorities charged Treu with four counts of homicide by negligent use of a motor vehicle, five counts of hit-and-run and four counts of homicide while intoxicated (use of inhalants), police said.
Authorities continue to investigate.
