"It's going to be extremely emotional," said Caleb's father, Stephen Quick. Attorneys met virtually Tuesday to discuss trial logistics and other pretrial matters.
The proceedings will continue Thursday after a judge granted a two-day continuance.
Prosecutors allege the girl was driving a white Tesla on the night of Quick's death in April 2025 and helped the suspected gunman, her boyfriend, flee the scene after the shooting.
Days after the killing, law enforcement seized the vehicle and briefly detained the girl.
She has since remained in custody at the juvenile justice center without bail.
For Stephen Quick, Tuesday's hearing marked another step in a process that has stretched more than 15 months.
"we kind of threw everything at the transfer hearing. Like really, that was a pivotal moment to really receive justice or not," he said.
The case comes more than two months after prosecutors pursued a weeks-long effort to have the girl transferred to adult criminal court.
A judge ultimately ruled that she would remain in the juvenile system.
Action News legal analyst Tony Capozzi said the decision carries major implications for any potential sentence.
"Conviction in the adult court, she's looking at 26 years to life for this offense.
But being in that juvenile court changes the landscape completely," Capozzi said.
Because the case is being handled in juvenile court, the girl's maximum period of confinement would be significantly limited.
According to Capozzi, she could only be held until age 25 before being released. Those provisions are part of California's Proposition 57.
"If she is determined to have been rehabilitated, she could be released a lot earlier than age 25, so a lot remains to be seen," Capozzi said.
Stephen Quick said he believes California's laws need to change.
"Sympathy for criminals means there's no justice for the victims," he said. Once the trial begins, attorneys expect the proceedings to last approximately 10 days.
The transfer hearing for the teenage boy accused of being the shooter is scheduled for September.
