Olaska entered his plea at an arraignment in DuPage County Court on Monday.

Prosecutors say Olaska stabbed another man, William Hayes III, in the chest with a 5-inch folding knife, after Hayes allegedly teased him about drinking beer from a wineglass.

Wild was stabbed in the heart when he tried to intervene.

Olaska also allegedly stabbed a third man, bouncer Rafael Castenada.

Wild was in his first year as a second grade teacher at Spring Brook Elementary School in Naperville.

Olaska has been indicted on 14 counts, including seven counts of first-degree murder.

His attorneys have made a motion to get his bond reduced, but prosecutors are fighting the effort.
