Three people are in serious condition following a high-speed chase in Moody County Thursday night.
Sheriff's officials tried to pull over the vehicle after receiving a call about a black Chevy Blazer driving erratically and at excessive speeds on Interstate 29 near Moody County.
That's when the chase started. The driver got off the interstate at the Flandreau exit and headed south on 478th Street through Trent.
A Sheriff's deputy says the driver lost control about two miles south of Trent, rolled and hit a tree.
The man who was driving and both female passengers were trapped in the Blazer and have serious injuries; two of them had to be airlifted to the hospital.
No names have been released as authorities still investigate. They do believe alcohol was a factor.
