Juan Moxthe, a 45-year-old man from Wood Dale, was allegedly driving a vehicle with three family members inside when it crashed last Sunday, authorities said.
The crash happened around 2:30 a.m. in the 12100 block of West Irving Park Road in Bensenville, Chicago police said.
The vehicle crashed into a median guard rail and flipped several times. A woman, ejected from the vehicle, was taken to a hospital, where she was pronounced dead.
Moxthe was allegedly driving with a 0.12 BAC level, which is over the legal limit of 0.08, authorities said.
"Like all alleged DUI cases, the case against Mr. Moxthe was 100% avoidable," DuPage County State's Attorney Robert Berlin said in a news release. "As I have said many times before, if you have been drinking, do not get behind the wheel of a car."
The Cook County Medical Examiner's Office later identified the woman as 28-year-old Jaylene Escamilla of Addison, Illinois.
Escamilla was the stepdaughter of Moxthe, authorities said.
Two other people who were in the car, a 50-year-old woman, Moxthe's wife, and a 30-year-old man, who is Escamilla's husband. They were treated by paramedics at the scene, police said.
Moxthe, seriously injured in the crash, was initially taken to a hospital.
He is due in court on Jan. 8.
