Police say Schellenger was riding with two others in a Mercedes-Benz when a confrontation ensued with White. Police say he pulled knife from his backpack and stabbed Schellenger.

Greg Thompson, a spokesman for White’s family, says he acted in self-defense.

He says White kept a knife in his backpack for protection because he delivered food late into the night.
