IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

SECOND APPELLATE DISTRICT

DIVISION EIGHT

THE PEOPLE, B334738

Plaintiff and Respondent, (Los Angeles County Super. Ct. No. BA490264) v.

RONNELL JAMAL THOMPSON,

Defendant and Appellant.

APPEAL from a judgment of the Superior Court of Los Angeles County, Mark K. Hanasono, Judge. Affirmed as modified. Theresa Osterman Stevenson, under appointment by the Court of Appeal, for Defendant and Appellant. Rob Bonta, Attorney General, Lance E. Winters, Chief Assistant Attorney General, Susan Sullivan Pithey, Assistant Attorney General, Steven D. Matthews and Rama R. Maline, Deputy Attorneys General, for Plaintiff and Respondent.

__________________________ Ronnell J. Thompson appeals from his conviction for second-degree murder and gross vehicular manslaughter. He raises four claims: First, that the trial court abused its discretion by admitting blood alcohol toxicology results from his diagnostic, rather than forensic, blood test. Second, that the court incorrectly instructed the jury regarding implied malice as is required for a murder conviction. Third, that the evidence was insufficient to support second-degree murder. And fourth, that he deserved additional presentence custody credits. We agree that Thompson deserves an additional day of presentence custody credits but otherwise affirm. FACTS AND PROCEDURAL BACKGROUND On October 19, 2019, Thompson’s car collided with Diane Wilson Yeboah’s van near the 48th Street and Western Avenue intersection in Los Angeles. Thompson drove between 88 and 92.6 mph in a 35-mph zone seconds before the collision, slowed down to between 60 and 73 mph at the point of the collision, and had a blood alcohol content (BAC) between 0.131 and 0.149. Yeboah died four days later from injuries sustained during the collision. The Los Angeles County District Attorney then charged Thompson with murder (Pen. Code, § 187, subd. (a)),1 gross vehicular manslaughter while intoxicated (§ 191.5, subd. (a)), driving under the influence of alcohol and driving with a .08 percent BAC, both causing injury within 10 years of another DUI offense (Veh. Code, § 23153, subd. (a)). Thompson moved pretrial to suppress his toxicology results on the grounds that the evidence was not sufficiently reliable under People v. Williams (2002) 28 Cal.4th 408 (Williams).

1 Further undesignated statutory references are to the Penal Code.

2 The court held an evidentiary hearing and denied the motion, finding Thompson’s argument to be “more properly the subject of a motion to exclude evidence . . . pursuant to Evidence Code [section] 402, rather than a motion to suppress evidence[.]” Thompson then filed a motion in limine pursuant to Evidence Code section 402 to exclude his toxicology results. The defense argued that the prosecution could not identify who drew Thompson’s blood, which meant the blood draw was unreliable, there was no chain of custody for the blood sample, and the prosecution could not establish the foundational requirements to admit the blood test results under Williams. The defense did not cite or argue that the evidence should have been excluded under People v. Kelly (1976) 17 Cal.3d 24 (Kelly). The court held an evidentiary hearing, discussed in more detail below, and denied the motion. The case proceeded to trial, and the trial evidence established the following. Thompson had been convicted of a previous misdemeanor DUI in 2016. The court there admonished Thompson that he could be charged with murder if he continued to drive under the influence of alcohol and caused someone’s death, as required by People v. Watson (1981) 30 Cal.3d 290 (Watson). Thompson’s sentence included participation in both an alcohol and drug program and a victim impact program from Mothers Against Drunk Driving. Both programs included Watson admonishments. Thompson was again arrested for driving under the influence in June 2019.2 After the June 2019 arrest, his license was suspended.

2 Thompson was convicted for driving under the influence for the June 2019 incident, but that conviction occurred after this collision in October 2019.

3 On the date of the collision, Thompson was driving a borrowed car. Meanwhile, Yeboah had picked up her grandson from Ed’s Market where he worked as a cashier to drive him home. As Yeboah exited the employee parking lot through an alley, she either stopped or slowed as she approached to make a left on to Western Avenue. As Yeboah’s van entered Western Avenue, Thompson’s car collided with the van, and the van was then hit by another car. The crash occurred around 8:20 p.m. Yeboah died four days later, and her grandson sustained injuries from the crash. Thompson was taken to the hospital and had his blood drawn. The nurse that drew Thompson’s blood at the hospital did not testify. Instead, the Director of Nursing and Emergency Services at the hospital testified that registered nurses ordinarily drew blood from trauma patients. She also testified to the training and qualifications such nurses received, how registered nurses draw blood from trauma patients, and how blood samples are labeled to ensure they match the correct patient. The hospital ordered an ethanol (alcohol) test on Thompson’s blood at 9:09 p.m. Thompson’s blood was then sent to the hospital’s internal diagnostic laboratory. The laboratory scientist that performed the analysis did not testify. Instead, the hospital’s lab director testified to the licensure, training, and qualifications of the lab personnel. He also testified about how an ethanol test is performed: First, the certified laboratory scientist (CLS) verifies the label to ensure it matches the test order. Second, the CLS places the blood sample vial into a centrifuge that spins the sample to separate the serum (or plasma) from the whole blood sample because the lab’s testing machine analyzes blood serum not whole blood. Third, the CLS

4 places the vial into the testing machine and presses a button. The machine then records the intensity of light emitting from an enzymatic reaction on the serum and uploads the results to the patient’s medical record. The lab director also testified that the lab conducts daily maintenance on the machine, calibrates the machine, and maintains its licensing as a diagnostic lab. Thompson’s blood serum had 0.164 grams of ethanol per deciliter. The hospital destroyed Thompson’s blood sample before it could be tested by a forensic lab. Los Angeles Police Department (LAPD) Criminalist Mandel Medina testified about how to convert that serum result into a whole blood result, because serum contains a higher concentration of alcohol than whole blood. Using a conversion ratio of 1.10 to 1.25, he testified that Thompson’s whole BAC range was 0.131 to 0.149 grams per deciliter, which was over the legal limit of 0.08 grams per deciliter. Medina further testified to his opinion that all drivers with a BAC of 0.08 and above are “too impaired to operate a motor vehicle safely.” Yeboah’s blood was collected at the hospital and later tested at LAPD’s forensic department following her death. LAPD’s certified forensic lab tested her whole blood for ethanol using a forensically approved gas chromatography test. She had a BAC of 0.108 grams per deciliter and a THC level of 0.14 nanograms per milliliter. LAPD Investigator Brandon Jeon conducted a crash reconstruction. The investigation used the data stored in the event data recorder module of Thompson’s car to help determine speed.
