One man is in the hospital with life-threatening injuries and another is behind bars after a hit and run crash. It happened near the intersection of 41st and Western Avenue just after 1 a.m. Friday. 

Twenty-nine-year-old Eric Oldre was arrested more than seven hours after the collision and charged with vehicular battery, leaving the scene of an accident, and his third DUI. 

Twenty-one-year-old Beau F. Brady of Yankton was critically injured in the crash. Police say Brady was crossing the street at the instersection of 41st and Western Avenue. A witness who saw the accident says he saw Brady, but Oldre showed no signs of slowing down.

John Geiken got off work at the Ground Round around one Friday morning, and had just pulled onto 41st Street.

"It just happened so fast, and when it was happening it was just almost like a surreal moment that you couldn't believe you were seeing what happened," Geiken said.

Geiken says he wasn't able to get a license plate number for the car that hit Brady but did tell police the make and model of the car and noticed the headlight was broken.

"He had to take off on a side street immediately after hitting him because I didn't see a car down 41st street or any of the parking lots nearby," Geiken said.

Around eight-thirty Friday morning police got a tip that someone had seen a car matching that description in the parking lot of a Sioux Falls apartment complex.

"It's tips like that that solve crimes like this and others, every citizen is another set of eyes out there for us to solve these things," Lt. Jerome Miller of the Sioux Falls Police department said.

And while Geiken's tip helped police catch up with the suspect, it's a sight he won't forget any time soon.

"I don't think I'll ever forget that," Geiken said.

Oldre is facing his third DUI, but  KELOLAND News has learned that after his second DUI all but 40 days of his jail sentence was suspended as long as he didn't drive drunk, leave the scene of an accident, or wasn't involved in a hit and run accident. Those conditions expired just ten months ago in December.
