CHICAGO (WLS) -- Judge Vincent Gaughan decided Friday to defer the decision to change the venue of the Jason Van Dyke murder trial.
It will be during the preliminary examination of potential jurors that the judge will hear if those potential jurors have a bias or if they can be impartial during a trial.
Judge Gaughan said today that if that process can go ahead and they can find those impartial jurors, they will move forward. But at this point, he will defer any decision on change of venue. The trial will begin on Sept. 5 in Cook County.
Van Dyke is accused of murdering Laquan McDonald in 2014.
Attorneys for Van Dyke argued during the hearing Friday his murder trial should be moved outside of Cook County.
Van Dyke's attorneys argued he cannot get fair trial in Cook County because of the case's publicity. The expert on the stand cited television, newspaper and social media coverage that could taint a jury pool.
His attorneys hired a social psychologist to determine the impact of attention to the case on potential jurors.
A trial expert testified about news coverage of the case and opinions of prospective jurors in Cook County.
The Special Prosecutor argued that Cook County is large enough and diverse enough to find impartial jurors.

Under cross-examination expert Bryan Edelman acknowledged that some surveyed shared they had no opinion on Van Dyke.
The expert for the defense also surveyed prospective jurors in Lake and Madison counties. He said of those two counties, Madison would be a better location because fewer of those surveyed knew much about this case and had not formed an opinion, but that expert did stop short of making a recommendation about where that trial should be held. Judge Vincent Gaughan will make that determination.
It's unclear if the judge will make a decision Friday.
On Tuesday, they asked to bring in a different judge to decide whether or not to move the trial. That motion was denied.
