Utah County sheriff's Sgt. Cory Wride was killed on a road near Lehi; Utah County sheriff's Deputy Greg Sherwood was wounded in Santaquin.
Zabriskie notes in his motion that much of the news coverage "has highlighted what a great loss the Utah County community has suffered with the death of this deputy."
"Both officers who were shot ... are now recognized as heroes, in part, due to this incident," Zabriskie adds.
Pead said outside of court on Monday that prosecutors needed more time to evaluate what has been published in the media, and how the fact that the victims were police officers could sway a potential Utah County juror.
"I think in that sense, it's a pretty unique situation," Pead said.
Zabriskie said in his motion that the 3rd District Court in West Jordan appears the most appropriate place to hold the trial, not only because of its close proximity to Utah County, but also because Salt Lake County offers "a large and diverse jury pool ..."
The teen will be back in court July 21.
Earlier this month, prosecutors and defense attorneys said that settlement negotiations were being discussed for Grunwald, but Zabriskie said he didn't believe a plea deal was a "viable alternative" at that time.
Zabriskie said if a settlement is not reached, he anticipates a trial in late fall.
The teenage Draper girl charged as an adult has pleaded not guilty to 10 felonies and two misdemeanors for the Jan. 30 events that also left her boyfriend, 27-year-old Jose Angel Garcia-Jauregui, dead.
Grunwald is charged with aggravated murder for the Wride's Jan. 30 death, and attempted aggravated murder for the wounding of Sherwood.
She also faces two counts of discharge of a firearm, two counts of attempted aggravated murder and aggravated robbery all first-degree felonies as well as obstructing justice, failure to respond to an officer, possession or use of a controlled substance and lesser charges of felony discharge of a firearm and misdemeanor criminal mischief and violation of operator duties after an accident.
Grunwald could be sentenced to up to life in prison if convicted. She is being held at the Salt Lake County jail on a $1 million cash-only bail.
She was ordered in April to stand trial after a judge found there was enough probable cause in dash-cam footage, photographs and witness testimony to move the case forward.
