The Fresno County District Attorney’s Office and the defense attorneys for one of the accused killers of Caleb Quick of Clovis presented their cases at the beginning of the month and the closing arguments are set for Monday, when a judge may also hand down a ruling.

The juvenile murder trial of Cassandra Michael wrapped its first week in Fresno County Superior Court, with prosecutors laying out a revenge plot they say ended in the execution-style shooting of 18-year-old Caleb Quick outside a Clovis McDonald’s. Michael, now 18, is accused of driving her boyfriend Byron Rangel to and from the April 23, 2025, killing when both teens were 16.

Here are key takeaways:

Friends of Quick testified they tried to stop the bleeding after a person dressed in all black shot him in the back of the head at close range in a McDonald’s parking lot, during the first day of witness testimony.A close friend of Michael’s since second grade said she left McDonald’s with Rangel that night and returned alone shortly after, then brought up rumors that Quick had sexually assaulted one of her friends.Text messages between Michael and Rangel from the day before and after the killing were read in court, with Michael writing “Idk how to feel” and “I’m just in shock honestly” in the hours after Quick was shot, as detailed by the lead Clovis detective.Byron Rangel’s older brother Hurley pleaded the Fifth Amendment at least 13 times when questioned about driving an upset Michael home and about two revolvers taken from the Rangel home, on the fourth day of trial.The alleged victim of the sexual assault, referred to as Jane Doe, testified that when she told Michael what happened, Michael hugged her and said, “I’m so sorry,” and that she never heard Michael talk about wanting revenge on Quick, as the defense opened its case Friday.A California Department of Justice criminalist testified that DNA from both Michael and Rangel was found on the silver Smith & Wesson revolver, though he acknowledged DNA can transfer through secondary contact without someone directly touching the gun, under questioning from the defense.A spent shell casing found in Byron Rangel’s closet was matched using firing pin markings to the silver .357 Smith & Wesson Magnum revolver taken from the Rangel home, though the bullet that struck Quick was never recovered, according to a senior state criminalist.A former Clovis police analyst testified Rangel searched his phone for “when does footage in the Tesla delete” and googled his own name twice in the days after the killing, while no similar searches were found on Michael’s phone, as the prosecution closed its case.Closing arguments are set for 10:30 a.m. Aug. 17 in Department 50, with Judge Brian Alvarez serving as the finder of fact after Michael was ordered to remain in the juvenile system rather than be tried as an adult, following a May transfer hearing ruling.
