LA GRANGE COUNTY, Ind. -- The La Grange County Sheriff's Department is asking for the public's help locating a vehicle involved in a crash that injured a bicyclist Thursday morning.

The vehicle was eastbound on CR600 S and the victim, 69-year-old Perry Fry, was riding a bicycle in the same location.

Deputies say the vehicle's passenger side mirror struck Fry and knocked him off his bicycle.

The vehicle left the scene of the crash.

A passerby stopped and assisted Fry, who suffered a shoulder injury and possible concussion.

Officers from multiple agencies searched for the vehicle but were unable to locate it.

The suspect's vehicle is possibly a GMC or Chevrolet.

The model, possibly between 1999 and 2006, could be a Sierra, Tahoe, Avalanche or Silverado.

The vehicle will likely have damage to the passenger side mirror.

If you have any information in this case, please contact the LaGrange County Sheriff’s Department at (260) 463-7491.
