A 3rd District judge on Thursday indefinitely delayed a first-degree murder trial while the Utah Supreme Court decides whether to hear defense claims that Salt Lake County's jury pool selection process is unconstitutional.

Jury selection had begun Wednesday in the trial for David Franklin Young, accused of murdering Ember Kimberly Mars in August 1987.But defense attorneys Karen Stam and Nancy Bergeson tried to get Judge Timothy Hanson to delay the trial, arguing that the jury pool process is unconstitutional because it doesn't allow a proportionate number of Hispanics and other minorities to be called as potential jurors.

Minorities, defense attorneys claim, are less likely to hand a defendant the death penalty.

Hanson denied the motion Tuesday, so defense attorneys filed a petition on the matter Wednesday to the Utah Supreme Court.
