A Waterloo man is critically injured after falling about 50 feet as he reportedly fled from a crash.
The single-car accident happened around 8:30 Monday evening along Interstate 255 just west of Illinois Route 3.
Illinois State Police have identified the driver as 21 year old Thomas Falk.
Witnesses told police that Falk appeared to have a head injury when he got out of his car. Police say Falk argued with someone who had reported the crash to police, then jumped over a guardrail and fell to the railroad tracks below.
Falk was taken to St. Louis University Hospital by Arch helicopter. His condition is reported to be very critical.
The St. Louis Post-Dispatch reports that 43 year old Mark Mihal had been standing on the 14th fairway when the ground swallowed him up. He landed in a bell-shaped hole, about 18-feet deep.
The course manager and Mihal's golfing companions used a ladder and some rope to pull him out.
Sinkholes are common in the St. Louis Metro area, but geologists say they are usually easy to spot because of a dent in the ground.
