The Camry was found in a wooded area just north of the toll road in Portage Tuesday.
Authorities are still looking for the man driving it and his female passenger. They're accused of hitting Trooper George Hornsby Monday. He had to have leg surgery.
The car had been reported stolen to Gary police last week.
A motorist notified police at 6:27 p.m. Monday of a hit-and-run crash in the westbound lanes of the Indiana East-West Toll Road near the LaPorte State Road 39 exit, according to an Indiana State Police release.
Trooper Ron Davidson saw the 2003 Toyota Camry traveling west on the Toll Road attempted to stop the car, the release said. The silver four-door car started to pull over then took off.
The car later struck Hornsby, 30, on the westbound Toll Road near the Portage, Ind., exit, the release said. The car did not stop and exited at Willowcreek Road in Portage and fled north.
The trooper was waiting behind his police car to deploy his stop sticks when the car approached, the release said. Hornsby, a two-year State Police veteran, attempted to throw the stop sticks when the car swerved to the right and hit him.
The trooper was taken to North Lake Hospital in Gary, Ind., where he underwent surgery late Monday on his leg, according to Indiana State Police Sgt. Ann Wojas.
