CASEYVILLE, IL (KPLR) - Three men and a woman are in custody Monday morning after a pre-dawn police chase ends in Caseyville, Illinois.

Three males and one female were wanted in connection with a robbery at the Mobil On Run located in the 13000 block of Riverport Drive in Maryland Heights. One suspect allegedly pointed a knife at the gas station attendant and demanded money. They reportedly fled the scene in an older model Pontiac Bonneville.

The high-speed chase began on westbound I-70, moved to eastbound I-70 from Jennings Station Road, and then back onto westbound I-70 before crossing over the Stan Musial Veterans Memorial Bridge.

The suspects continued onto eastbound I-64 to Highway 157 in Caseyville.  After traveling through several streets in the area, they eventually crashed into a ditch while attempting to drive up a hill.

All four people in the vehicle were apprehended. The female in the vehicle was loaded into an ambulance and taken from the crash scene.
