Details on motive behind Caleb Quick slaying emerge as judge backs murder charge
It remains unclear whether the accused getaway driver in the Caleb Quick slaying will be tried as an adult, though a judge said prosecutors presented enough evidence to seek a murder conviction against now-17-year-old Cassandra Michael.
Judge Kimberly A. Gaab made the declaration Wednesday at a hearing that included new information on the motive behind the killing of 18-year-old Quick. Gaab said Michael will be held for trial to face a murder charge and an enhancement as a co-participant in a crime involving a gun.
Prosecutors allege Michael acted as the getaway driver for her boyfriend, Byron Rangel, on April 23, 2025, when the teen boy fatally shot Quick in the back of the head outside a Clovis McDonald’s, a popular teen hangout. Both teens were 16 when accused of the crime.
The couple was seen on video at the McDonald’s with friends around 7:45 p.m. that night for a weekly hangout they called “Fry Night.” They left before Michael returned later alone in her car. Rangel arrived after that on foot, now dressed in all black and wearing a mask, prosecutors have said.
Gaab said the Fresno County District Attorney’s Office case had no direct text messages or statement by Michael about killing or committing violence on Quick, but did have phone records, surveillance video, testimony and other evidence surrounding the night in question.
“There is, to be frank, overwhelming circumstantial evidence in this case,” Gaab said in court Wednesday on the second day of Michael’s transfer hearing.
The transfer hearing will determine whether Michael should be tried as a minor or an adult. The hearing has run concurrently with a prima facie case, which is the juvenile court’s version of a preliminary hearing in an adult criminal case.
The hearing was expected to continue until at least Friday to answer the transfer question.
Senior District Attorney Kendall Reynolds said the crime began the day before the shooting, when Michael discussed the allegations of rape against Quick, the shooting victim. Reynolds argued Michael lied on behalf of Rangel, drove him to where he changed clothes and armed himself, and then picked him up as he fled.
“Cassandra is equally culpable, given her conduct,” Reynolds said in court.
One of Michael’s attorneys, Sally Vecchiarelli, argued the prosecution’s case had holes that were missing evidence.
“Their job is to figure out what happened to that, not just guess, which is what they’re doing,” she said in court.
Vecchiarelli argued Michael had talked about the allegations of rape — which were well known among their friend group — because she had just learned of them and did not repeat them to be inflammatory. There were also almost 20 minutes when phone records showed the teens were not together that Vecchiarelli argued was when Rangel changed his clothes and armed himself away from Michael.
Ultimately, the judge sided with the prosecution that Michael will face the murder charge rather than a lesser charge like being an accessory after the fact.
Evidence surrounding murder case and rape allegation against Quick
On the first day of the trial Tuesday, Clovis police testified they found a spent shell casing in Rangel’s closet in the family’s Clovis home while serving a search warrant.
The shell casing could not be matched to a projectile that struck Quick, because Clovis police said they never found the projectile. But the markings on the shell were matched to those fired by the silver .357 Smith & Wesson Magnum revolver found in Rangel’s home, according to Greg Masters, a senior analyst with the state Department of Justice.
Clovis Det. Lovedeep Malhi said phone records showed Rangel shared his location on his phone with Michael about a half hour before the slaying.
Clovis police Det. Emily Eide said she determined in an interview with Rangel’s older brother, Hurley Rangel, the .357 had been left to the younger Rangel by their grandfather when he died. That gun along with another left to the elder brother were in the family home, and the younger Rangel had previously found where they were kept, Eide said.
The couple had arrived to the Rangel family home about 9:30 p.m. April 23 — about 30 minutes after the killing of Quick — and told the elder Rangel they had just been at McDonald’s on Willow and Nees avenues.
“They came in and told him Caleb had died,” Eide said. “He described Cassie as being shaken up, crying and inconsolable.”
He described his younger brother as less upset than Michael, but said he was frantic and not making eye contact though said that was not unusual.
“He couldn’t see (Byron) killing Caleb, but he could see him doing something bad, because Byron was irrational,” Eide said.
The brother said Rangel had been in two fights at school. Eide said Rangel could no longer attend Clovis North High School as a result of one fight. The second fight took place at Gateway High School, a continuation school.
Eide said she spoke with a number of the teen couple’s friends. One of them said Michael had tried to give her Tesla away to him in the days following the shooting, saying Michael said the car was having mechanical problems.
More than one friend described Michael as visibly upset at a prayer vigil for Quick in the days after the shooting. Seeing Quick’s body “was all (Michael) could think about,” Eide said one of the teens told her.
The detective also spoke to a classmate of Rangel’s at Gateway, who told Eide that Rangel never specifically said he shot Quick but alluded to it.
“(Byron) said, ‘I did it to him,’“ Eide said, recounting the classmate’s words. “He described that Byron was concerned with being caught, but he was content with the outcome because he did what he needed to do to get justice.”
Vecchiarelli asked Eide about the witness statements. Eide confirmed Rangel spoke of the alleged incident and his own actions, never saying “we” or describing Michael as being involved in the shooting.
In her closing arguments for the prima facie case, Vecchiarelli argued that Rangel may have worked with the Gateway classmate to commit the crime. She noted Eide asked that student about Rangel’s change of clothes that was never found as well as the gun used in the slaying.
Investigators said they believe the shooting was retribution for an alleged sexual assault by Quick.
Eide also collected information on a potential motive with more than one of the teens sharing they’d heard rumors and allegations that Quick had sexually assaulted a drunk teenage girl who was the sister of Michael’s friend. Eide spoke to the alleged rape victim, who said Quick “was like a brother to me.”
The girl’s statement to police at one point described the encounter as sexual assault while at another time the girl said she wasn’t sure if she consented, Eide said.
The alleged sexual assault occurred April 13, 2025, after a party. The victim said she had six or seven drinks of beer and shots and by 2 a.m. had fallen asleep on a chair and then on the grass in a yard, Eide confirmed.
Quick was supposed to take her home and police later found videos of the alleged assault on his phone, according to previous testimony by Clovis police.
Fresno County Juvenile Justice Campus teacher Timothy Allison testified Michael was an excellent student since joining his classroom in May 2025.
The hearing was set to continue on Thursday.
Rangel is due back in court on June 9. His transfer hearing has not been set.
