DNA testing can be done on two blood stains found on the knife authorities allege Daniel Olaska used to kill Naperville school teacher Shaun Wild, a DuPage County judge ruled Monday.

Prosecutors sought the genetic testing on the 5-inch-long folding knife to confirm it was the weapon used to kill Wild and wound two other men during a deadly Feb. 4 clash in a Naperville nightclub.

Judge Kathryn Creswell agreed to allow the testing after Olaska didnt object to testing the weapon, which was found by police in Frankies Blue Room after the late-night stabbings.

The DNA testing isnt crucial because security cameras captured the stabbings, which also were witnessed by other nightclub patrons, defense attorney Brian Telander said.

I dont think the results will be relevant. Its not a who-dunit, said Telander, who has hinted he will argue the stabbings occurred in self-defense during an altercation.

Olaska, 27, is charged with fatally stabbing the 24-year-old Wild, as well as wounding Wilds friend, 22-year-old William Hayes, and bar bouncer Rafael Castenada.

Olaska was arrested as he tried to leave the bar with other clubgoers after the 12:45 a.m. stabbings.
