(UNDATED) – An Auburn man is in critical condition following a single vehicle crash.

Indiana State Police say they were called to a crash in the 400 block of County Road 68 in DeKalb County at 6 PM Monday. Troopers arrived and found a vehicle that went off the road and crashed head on into a tree. The driver, 58 year old Steven Lemmon of Auburn, had several serious injuries.

Lemmon was treated at the scene by the LaOtto Fire Department and DeKalb Parkview EMS and then transported to Parkview Regional Medical Center in Fort Wayne.

Preliminary investigation revealed that Lemmon was traveling east on County Road 68 when for a still unknown reason he ran off the roadway and struck the tree, which was four foot in diameter. There was no indication of braking or other evasive action taken prior to impact.

Lemmon was wearing his seat belt, and airbags in the vehicle did activate. Excessive speed was a factor in the crash, which remains under investigation.
