FIRST APPELLATE DISTRICT

DIVISION TWO

THE PEOPLE, Plaintiff and Respondent, A170747 v. JERMAINE JEREMIAH BRIM, (Alameda County Super. Ct. No. 19CR017660) Defendant and Appellant.

Defendant Jermaine Brim boarded a BART train and got into a physical fight with another passenger, Oliver Williams. The fight lasted some five minutes, and during it Williams drew a knife and attempted to stab Brim. The fight continued and eventually Brim gained control of the knife, fatally stabbed Williams in the head and neck, and ran from the train. The entire altercation was captured on two BART surveillance cameras. Brim was charged with murder and tried by jury, where he testified that he had acted in self-defense. After lengthy deliberations over three days, during which the jury asked several insightful questions of the court, the jury found him guilty of second degree murder and he was later sentenced to 16 years to life in prison. Brim argues that the trial court erred in: (1) stationing an armed deputy near him during his testimony; (2) instructing the jury with CALCRIM No. 3474 regarding the right to self-defense, and in responding to the jury’s question about that instruction during its deliberations; and (3) in limiting the jury’s consideration of his diminished intellectual capacity by instructing it with CALCRIM No. 3428. We agree

1 that the trial court prejudicially erred in responding to the jury’s question regarding CALCRIM No. 3474, and we therefore reverse Brim’s murder conviction. However, because we also conclude that there is substantial evidence to support that conviction, the People may retry Brim for murder. If they elect not to do so, we direct that the judgment be modified to reflect a conviction for voluntary manslaughter.1 BACKGROUND The Altercation on BART Around 1:00 p.m. on November 19, 2019, Brim boarded a BART train at the San Leandro station. At the time, he was not wearing shoes. What happened next was captured on at least two BART surveillance cameras.2 We have reviewed the video from those two cameras, and find the following description of their contents in Brim’s later-filed motion for acquittal to be generally accurate, except as noted: “Broadly speaking, the video depicts Mr. Brim enter the BART, take a seat in car 303 and have no interaction with anyone. He then enters car 1732 where he approaches a gentleman who appears to be sleeping and touches his shoe. As he touche[s] the shoe, the gentleman stirs and Mr. [Oliver] Williams turns his head and appears to be listening to what is being said. The video then shows Mr. Brim pull one of the man’s shoes off and Mr. Williams look in his direction. Mr. Williams then gets up and he and Mr. Brim[ ]appear to

1 Our disposition makes it unnecessary for us to reach Brim’s other two arguments on appeal. Those arguments do not relate to the only difference between perfect and imperfect self-defense—the objective reasonableness of the defendant’s belief that deadly force was necessary to save his own life— nor does Brim contend otherwise. 2 The record includes five videos: two videos from each of two cameras on BART car 1732, and one video from BART car 303, showing four angles.

2 exchange some sort of words. Mr. Brim walks around and away from Mr. Williams and begins to stop and speak to [a passenger] wearing [a] camouflage jacket. The gentleman in the camouflage jacket sits up as Mr. Brim stops and Mr. Williams comes toward Mr. Brim saying something and gesturing for him to leave the car. Mr. Brim then leaves the car and Mr. Williams stands in the doorway of car 1732 as he does. “Not too long after . . . Mr. Brim reenters the car and he and Mr. Williams begin fighting. At the very beginning of this 8 minute[3] fight, Mr. Brim is seen hitting Mr. Williams several times in his body while Mr. Williams is on [a] yellow seat[,] and then again once they end up on the ground. Mr. Williams does not hit Mr. Brim back with his hands. When Mr. Brim hits Mr. Williams while they are on the ground, the video shows that Mr. Williams has a hold of Mr. Brim[’]s legs. Both of them are moving around. Mr. Williams then rolls and turns over using his boots. Mr. Brim’s leg is between Mr. Williams’ legs and the[y] continue to move around like this until the video shows Mr. Williams kick Mr. Brim in the chin face area with his boots. Mr. Brim begins grasping for Mr. Williams’ boots[,] and for a brief moment hold[s] them down toward the seat while Mr. Williams is on his back. Eventually, Mr. Brim and Mr. Williams are both on the ground with Mr. Brim’s legs between Mr. Williams’ legs and Mr. Brim and Mr. Williams are holding onto one another by the shirt. “The BART doors open and close. Mr. Brim has his right hand on the yellow seat and Mr. Williams begins reaching for his left pocket. Mr. Brim begins also reaching for the left pocket. Mr. Brim and Mr. Williams appear to

3 The video (until Brim leaves the train) is just over seven minutes long, and the fight itself occupies some five minutes.

3 say something before Mr. Williams pulls out a knife from his pocket. The video shows that he switches the knife to his right hand, kicks Mr. Brim back onto the yellow seat with his boots and tries to stab Mr. Brim in the leg area.[4] “Mr. Brim and Mr. Williams then begin struggling over the knife. Eventually the knife appears to fall to the ground and Mr. Brim picks it up and stabs Mr. Williams multiple times in the head area. Mr. Williams is moving around the whole time. The BART doors then open to the next stop and Mr. Brim gets up and runs from the BART train looking behind him as he runs.” Williams died shortly thereafter from loss of blood caused by multiple stab and incised5 wounds. Meanwhile, Brim left the South Hayward BART station, dropping a bloody glove on the stairs and a bloody sweater in the parking lot. He proceeded to a nearby AM/PM mini-mart and purchased a bottle of water, using it to wash blood off his hands and feet. He then went to a nearby car dealership, where Steve Castro, the sales manager, showed him a car for sale. After getting into the driver’s seat, Brim asked Castro for the keys, and ended up punching Castro and running away. He next stopped a moving car in the street and entered the passenger side door, causing the driver to take

4 In his closing argument, the prosecutor argued that “it’s pretty clear that when he pulls out the knife, he tries to stab Mr. Brim in the hand.” 5 According to the forensic pathologist who performed Williams’ autopsy, an incised wound “measures bigger or longer on the surface of the skin than . . . its depth into the body.”

4 the keys and flee. Brim exited the vehicle and ran to a nearby bus stop, where he was placed under arrest.6 The Charges On November 21, 2019, the Alameda County District Attorney filed a complaint, and on May 20, 2021, the operative information, charging Brim with Williams’ murder (Pen. Code,7 § 187). The information included the special allegations that Brim was on bail or released on his own recognizance at the time of the offense (§ 12022.1), and that during its commission he used a deadly weapon (§ 12022, subd. (b)(1)) and personally inflicted great bodily injury (§ 1203.075). The Trial A 15-day jury trial took place in August and September of 2023. The prosecution’s witnesses included Sophia Humphrey, a passenger who waited for the train near Brim and witnessed the fight; Wendy Cristy Alas Calles, an employee of the car dealership; Dr. Thomas Rogers, the forensic pathologist who performed Williams’ autopsy; and several police officers. The defense witnesses were Scott Ferreira, an expert in the area of “martial arts, self-defense and human behavior as it relates to human aggression”; Dr.
