FIFTH APPELLATE DISTRICT

THE PEOPLE , F089200 Plaintiff and Respondent, (Super. Ct. No. 20CMS-1621) v.

MARIO ALBERTO VALENZUELA, OPINION Defendant and Appellant.

APPEAL from a judgment of the Superior Court of Kings County. Marianne Gilbert, Judge. Denise Marie Rudasill, under appointment by the Court of Appeal, for Defendant and Appellant. Rob Bonta, Attorney General, Charles C. Ragland, Chief Assistant Attorney General, Kimberley A. Donohue, Assistant Attorney General, Darren K. Indermill and Kari Ricci Mueller, Deputy Attorneys General, for Plaintiff and Respondent. -ooOoo- INTRODUCTION A jury convicted Mario Alberto Valenzuela (appellant) of battery by a prisoner on a nonprisoner (Pen. Code, § 4501.5), 1 and appellant admitted three prior strike conviction allegations (§§ 667, subds. (b)–(i), 1170.12, subds. (a)–(d)). The trial court sentenced him to an indeterminate term of 25 years to life in state prison. On appeal, appellant contends the prosecutor committed misconduct during closing argument and that the trial court erred by failing to dismiss his prior strike convictions pursuant to section 1385, subdivision (c). We reject both contentions and affirm. BACKGROUND I. Prosecution Evidence. In June 2019, appellant was incarcerated at Corcoran State Prison. Christian S. was employed at the same institution as a correctional officer. A. June 5, 2019, Incident. On the morning of June 5, 2019, two correctional officers escorted appellant from his cell to a mental health group meeting. The officers testified that appellant was handcuffed but not in leg restraints. As they proceeded to the meeting room, they encountered Christian S., who was standing in a hallway. Without warning, appellant stepped forward with his left leg, then kicked with his right leg, striking Christian in the upper thigh area. According to the officers, Christian was “just standing there” and did not say or do anything to provoke the assault. The officers immediately took appellant to the ground, where he continued to thrash and kick until they succeeded in gaining control of him. Christian S. testified that he was assigned that morning to escort inmates to their mental health appointments. After several inmates declined to attend, he went to a

2. hallway and waited. While he was standing there, appellant kicked him in the upper left thigh. Christian explained that he had no prior history with appellant, did not know who he was at the time, and had no idea why appellant kicked him. Christian S. testified the kick caused pain and redness to the area of contact but did not result in further injury. Another officer took a photograph of Christian’s lower body, which depicted dirt on his pants in the area of contact. No photograph of the actual injury was taken. B. June 22, 2019, Incident. On the morning of June 22, 2019, Christian S. and correctional officer Jaime A. were assigned to collect breakfast trays from inmate cells following the morning meal. Christian testified they approached cell number 8, which was solely occupied by appellant. After opening the food port in the door of the cell, they instructed appellant to place his tray on the port, and he complied. When Christian reached for the tray, appellant suddenly thrust his right arm through the food port and began making slashing motions. Christian could see appellant was holding something in his hand but could not determine what it was. Appellant struck Christian’s wrist and palm area, penetrating his glove and causing a laceration approximately three to four inches in length. Christian covered the wound with a paper towel to control the bleeding and sought medical treatment at the prison’s medical clinic, followed by treatment at a local hospital. Jaime A. testified he saw appellant thrust his hand through the food port and make slashing motions toward Christian S. Immediately after the assault, Christian attempted to back away from appellant’s cell, but a food cart blocked his path. In response, Jaime deployed a burst of pepper spray into the cell through the food port. Appellant stepped back from the cell door, and Jaime saw him throw an unknown object into the toilet and heard the toilet flush. Jaime A. activated an alarm, and several correctional officers responded. Appellant complied with orders to place his hands through the food port and was

3. handcuffed, but when officers opened the cell door, he pushed off the wall with his foot and lunged at an officer. The officer used appellant’s momentum to take him to the ground, causing him to strike his face on the concrete floor. Appellant continued to resist, thrash, and kick, repeatedly stating, “[M]otherfucker, … I got your fucking ass.” The officers did not locate a weapon. On cross-examination, defense counsel asked Jaime A. if there is a “procedure at the prison when contraband is thrown in the toilet.” Jaime responded there is no practical procedure for recovering contraband once an inmate, still inside the cell, begins flushing it. Although staff have the ability to shut off the water, doing so requires obtaining a key and accessing a lever behind a secured door. In this case, the water was not shut off because there was insufficient time. II. Defense Evidence. A. In-custody witnesses. Appellant called three in-custody witnesses, each of whom testified he was housed in the same area as appellant at Corcoran State Prison in June 2019 and knew appellant by the nickname “Huey.” D.P. described two incidents involving appellant in June 2019. The first incident occurred in a hallway. According to D.P., he was speaking with a doctor when he heard a commotion and, upon looking over, saw appellant fall forward. Christian S. and another correctional officer then kneed appellant in the back and slammed him to the ground. He did not observe the events leading to the incident. The second incident occurred later in the month while D.P. was in his cell, which was located two to three cells from appellant’s. He testified that, during tray collection, he observed several correctional officers outside appellant’s cell. After hearing one of the officers make a comment, he saw the officers open the food port and deploy pepper spray into the cell. He further testified he heard appellant ask, “[W]hy are you spraying me[?],” followed by the activation of an alarm. D.P. testified that several officers,

4. including Christian S., removed appellant from the cell in handcuffs, struck him, forced him to the ground, and that one officer used leg irons to “choke” appellant. He acknowledged he lacked a direct view of the entire incident but claimed he observed it through a reflection in a rolling plexiglass shield used by officers when deploying “gas” into a cell. He later observed bruising and blood on appellant’s face and saw him wearing a neck brace. He also claimed appellant never flushed his toilet. D.P. admitted prior convictions for kidnapping, rape, robbery, and criminal threats. He also admitted prior convictions for assaults on correctional officers, including a 2019 conviction for aggravated mayhem against a correctional officer. Rudy J. testified he was housed in the same building as appellant, but on the upper tier. Sometime in June 2019, he heard commotion on the bottom tier while he was in his cell.
