The teen is accused of shooting and killing 18-year-old Caleb Quick outside a Clovis McDonald's in April.
Investigators believe the suspect watched Quick for several minutes in the McDonald's before following him to the parking lot and shooting him, then leaving the scene with his girlfriend.
Action News is not naming the suspects because of their ages.
On Monday, the boy returned to court for a status hearing as a judge decides if his case will be transferred to adult court for the chance of a more severe sentence.
"We're still getting discovery, records and because there are juveniles involved, that takes a long time," said Mark Coleman, Attorney.
Under California's Proposition 57, if convicted as a minor, he could be released by his 25th birthday.
Caleb's father, Stephen Quick, said the suspects acted as adults and should be tried as such.
"This whole process is really frustrating because, obviously, my son didn't get due process. He just got murdered, he got assassinated in front of all of his friends," said Stephen.
The boy's attorney told Action News in the past that the incident may have been provoked by what he described as "egregious harm" allegedly committed by Caleb.

Stephen stood outside the courthouse alongside other families on Monday, where they called for change.
Julia Sanchez joined Stephen. Her son, 17-year-old Lorenzo Sanchez, was stabbed to death in April. The suspect in his case is a 15-year-old.
She continues to take part in protests because she said the group acts as a voice for the victims.
"If we are together, working together, it's going to make the change, us sticking together," said Sanchez. "It's sad, but I'm glad I'm not the only one because for a change, it takes a village."
The boy will return to court in October for another status hearing as part of the process to potentially move the case to adult court.
The other suspect was in court last month; her transfer hearing could extend into next year.
