Adegboye Oguntade, 31, of south suburban Lansing, was found near 69th and Racine. He had been shot and his car hit a light pole.
He worked for Jet Livery. The company's co-owner, Famien Morrison, says Oguntade was a pleasure to be around.
"All the time smiling, and also he always had a tendency of calling me, 'Yes, sir' - everything that came out of his mouth, 'Yes, sir'; one time I finally said, 'Listen, this is not an army - just call me Morris like everyone does," said Morrison.
Police say Oguntade was likely shot and subsequently crashed into the pole.
There were no suspects in custody early Sunday evening.
