IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

SECOND APPELLATE DISTRICT

DIVISION SIX

THE PEOPLE,

 Plaintiff and Respondent,

v.

RENE ROSAS,

 Defendant and Appellant.

2d Crim. No. B255739

(Super. Ct. No. F470906)

(San Luis Obispo County)

A jury found Rene Rosas guilty of vehicular manslaughter without 

gross negligence while intoxicated. (Pen. Code, § 191.5, subd. (b).) The court 

sentenced Rosas to four years and suspended the final year. We reverse. There is 

no evidence Rosas was driving at the time of the accident.

FACTS

Rosas brought his motor home to an auto repair shop owned by 

Ronald Kelsey in September 2010. Rosas had been having trouble with the motor 

home. It rolled when the transmission was placed in park.

Susan Booth, Kelsey's sister-in-law and employee, saw Rosas go into 

the motor home and Kelsey go under the driver's side rear tires. She saw Rosas 

start the motor home and the motor home roll backwards one to two feet onto 

Kelsey's back. Booth and Kelsey screamed. Rosas moved the motor home forward.

The screams brought another employee and two neighboring shop owners to the 

site. One of the neighboring shop owners saw Rosas behind the motor home 

steering wheel, "hanging out the window," asking "what happened?" The 

neighboring shop owners pulled Kelsey's body from under the mobile home and 

administered "C.P.R." until the police arrived. Kelsey died of blunt force trauma. 

His injuries were consistent with being crushed by a leveling jack stand under the 

motor home.

Sergeant Michael Martinez of the Arroyo Grande police department 

conducted an accident investigation. Martinez believed that a chock behind the 

front passenger tire was in place when the accident happened. It bore tire treads and 

had dirt pushed up against it. Other chocks were added after the accident. The 

motor home moved a total of 56 inches backward and 32 inches forward.

Rosas told the police that initially Kelsey got underneath the motor 

home and had Rosas shift through the gears while the engine was off. Then Kelsey 

told Rosas to do the same thing with the engine on. Rosas replied, "Are you crazy? 

Seriously? Kelsey responded, "Yeah. Just keep your foot on the brake? Rosas said 

he asked, "Are you sure?" and Kelsey replied, "Yeah."

Rosas started the engine. He said he had his foot on the brake when 

he put the motor home in gear. He said the transmission got stuck in reverse. He 

said the motor home moved even though he had his foot on the brake. Police drove 

the motor home after the incident. They found nothing wrong with the brakes.

Officer Vincent Johnson of the Arroyo Grande police department 

investigated Rosas for driving under the influence. Rosas admitted that he had 

taken a "couple of shots" of whiskey before the accident and that he felt "a little 

buzzed." Rosas also admitted that he had used marijuana earlier that day and used 

methamphetamine between one and three days before.

Johnson noticed Rosas' color was flushed, his eyes were bloodshot, 

his speech was slurred and he had the odor of alcohol on his person. Johnson 
3

conducted a field sobriety test. Rosas forgot the instructions for a part of the test 

and swayed during a balance test.

A blood test showed that Rosas had a blood alcohol level of .05, and 

0.33 milligrams per liter of methamphetamine. The therapeutic dose of 

methamphetamine is .01 to .05, and the potentially toxic level is .02 to .05. 

Toxicologist Bill Posey testified that high levels of methamphetamine can 

contribute to the effects of alcohol.

Defense

Mechanical Engineer, Michael Stapleford, testified for the defense. 

Based on the age of the motor home and Rosas' statement, Stapleford opined that 

the motor home suffered from master cylinder bypass. It allowed the motor home 

to roll even though Rosas had his foot on the brake.

Stapleford also testified there was only one small wheel chock in 

place at the time of the incident. That chock was not sufficient to keep the motor 

home from rolling. Industry standard is to use large steel or rubber chocks as high 

as 12 inches.

Stapleford testified that the industry standard is that the technician has 

primary responsibility for safety and customers are generally not allowed in work 

areas.

Drug and alcohol consultant Felix D'Amico testified he reviewed a 

video of the field sobriety test. He saw nothing in the test that indicated Rosas was 

under the influence. D'Amico also criticized the way Johnson conducted portions 

of the test.

Toxicologist Okorie Okorocha testified that a 0.33 methamphetamine 

level was not toxic for everybody and would not increase the effects of alcohol. At 

the time of the accident, Rosas' blood alcohol level could have been .02. Video of 

the field sobriety test showed Rosas was not impaired.

DISCUSSION

I.

Rosas contends there is no substantial evidence that he was driving at 

the time of the accident.

Penal Code section 191.5, subdivision (b) provides: "Vehicular 

manslaughter while intoxicated is the unlawful killing of a human being without 

malice aforethought, in the driving of a vehicle, where the driving was in violation 

of [s]ection 23140, 23152, or 23153 of the Vehicle Code, and the killing was either 

the proximate result of the commission of an unlawful act, not amounting to a 

felony, but without gross negligence, or the proximate result of the commission of a 

lawful act that might produce death, in an unlawful manner, but without gross 

negligence."

In reviewing the sufficiency of the evidence, we view the evidence in 

a light most favorable to the judgment. (People v. Johnson (1980) 26 Cal.3d 557, 

578.) We discard evidence that does not support the judgment as having been 

rejected by the trier of fact for lack of sufficient verity. (People v. Ryan (1999) 76 

Cal.App.4th 1304, 1316.) We have no power on appeal to reweigh the evidence or 

judge the credibility of witnesses. (People v. Stewart (2000) 77 Cal.App.4th 785, 

790.) We must affirm if we determine that any rational trier of fact could find the 

elements of the crime or enhancement beyond a reasonable doubt. (People v. 

Johnson, supra, at p. 578.)

Rosas cites Mercer v. Department of Motor Vehicles (1991) 53 Cal.3d 

753, for the proposition that driving requires a vehicle to undergo a volitional 

movement. In Mercer, the question was whether for the implied consent law to 

apply, the arresting officer must see the vehicle move. In holding that the arresting 

officer must see the vehicle move, the court noted that the offenses to which the 

implied consent law applies require the defendant "'to drive a vehicle.'" (Id. at p. 

759.) The court stated, "Any doubt about our understanding of the word 'drive' is 

dispelled by decades of case law holding that the word 'drive' when used in a drunk 
5

driving statute, requires evidence of a defendant's volitional movement of a vehicle. 

[Citations.]" (Id. at p. 764.)

Here there was no evidence of Rosas' volitional movement of the 

motor home. At the time of the accident Rosas was following, or at least attempting 

to follow, Kelsey's directions. Both Rosas and Kelsey were aware that if the motor 

home moved, it could have disastrous consequences. At least one wheel was 

chocked, albeit inadequately, to prevent movement. Neither Kelsey nor Rosas 

wanted the motor home to move.

The People argue Rosas knew the brakes were faulty. Rosas knew 

that the parking brake did not function and that the motor home would roll even 

with the transmission in park. But there is no evidence Rosas knew the motor home 

would move even when he had his foot on the brakes. In fact, the brakes worked 

when the police tried them.

The movement of the motor home was not volitional. There is no 

evidence Rosas was driving within the meaning of Penal Code section 191.5.

The judgment is reversed.
