One person was killed and four others were injured in a single-vehicle accident on Route 159 north of Edwardsville on Sunday, June 23.

Deon Miller Jr. of Alton was pronounced dead by the Madison County Coroner from injuries he suffered during the accident. He was 20 years old.

According to the state police, a 17-year-old East Alton woman was driving an SUV north on Route 159. The vehicle contained four passengers, including Miller. Investigators said that just before 2:30 a.m., the vehicle began to leave the roadway while negotiating a curve about a half mile south of Route 140. The driver over-corrected, causing the SUV to cross both lanes and leave the road before striking the ditch and overturning.

Miller, who was in the back seat, was ejected from the vehicle. Another passenger, 21-year-old Candice Graves of Alton, was airlifted from the scene and taken to a St. Louis area hospital with serious injuries.

The driver and the other two passengers, identified as 19-year-old Amari Price of Alton and 22-year-old Tyler Melton of Hartford, were all taken by ambulance to area hospitals with non-life threatening injuries.

The incident is still under investigation by Illinois State Police Zone 6 Investigations. No further information is being released at this time.
