Sioux Falls, SD (KELO-AM) A driver from Billings, Montana killed himself on an exit ramp on Interstate 29 in Sioux Falls on Wednesday.
Police Spokesman Sam Clemens says the man's truck veered off the highway for some reason, hit a light pole and came to rest. Clemens says that as several witnesses rushed to the truck to help, the man fatally stabbed himself in the chest with a knife.
Clemens says the man was apparently o-k from the crash - he stabbed himself after witnesses arrived at his vehicle.
