A Jackson County man was killed in a one-vehicle crash Tuesday afternoon in Jennings County.

Officer Seth Beville, Public Information Officer for the North Vernon Police Department, says that officers were called to the scene at 12:20 p.m. Investigators say that the driver, Aaron C. Brown, 39, of Seymour, was driving an SUV westbound on US 50 East, near Flintwood Drive, in North Vernon. A witness told police that, for unexplained reasons, Brown’s vehicle went left of the center yellow line, continued to drift across the left lane, eventually leaving the road and crashing into a tree, head-on. Investigators say that the impact caused the SUV to roll onto its passenger side.

Brown was pronounced dead at the scene. Police are still investigating the crash.
