Police on Monday were looking for the driver of a vehicle who they believe intentionally struck another man, critically wounding him in the early morning hours in Chicago's Jefferson Park neighborhood.
Paramedics said they found the injured 38-year-old man in an alley near the 5500 block of West Farragut Avenue shortly after 1 a.m.
The man apparently ended up in the alley after the motorist struck him a short distance away, in the 5200 block of North Loring Avenue, authorities said.
"I saw somebody being lifted into the ambulance, and I assumed it was maybe a health problem," said area resident John Thulin.
Paramedics took the man in critical condition to Advocate Lutheran General Hospital in Park Ridge, authorities said.
After initially looking into a report of a hit-and-run collision, detectives shifted their investigation to focus on an intentional attack, police said.
No one was in custody early Monday. A description of the vehicle, which fled northbound after the crash, was not released by investigators.
