COURT OF APPEAL, FOURTH APPELLATE DISTRICT

DIVISION ONE

STATE OF CALIFORNIA

THE PEOPLE, D085909

Plaintiff and Respondent, (Super. Ct. No. SCE422471)

v.

JOAN COOPER,

Defendant and Appellant.

APPEAL from a judgment of the Superior Court of San Diego County, Patricia K. Cookson, Judge. Affirmed. Marta I. Stanton, under appointment by the Court of Appeal, for Defendant and Appellant. Rob Bonta, Attorney General, Charles C. Ragland, Chief Assistant Attorney General, Arlene A. Sevidal, Assistant Attorney General, Andrew Mestman and James M. Toohey, Deputy Attorneys General, for Plaintiff and Respondent. I. INTRODUCTION

A jury found defendant Joan Cooper guilty of robbery (Pen. Code, § 211) after she hit and kicked security guards who tried to stop her from shoplifting from a grocery store. The trial court placed Cooper on two years’ formal probation. On appeal, Cooper contends the trial court erred by denying her midtrial motion to exclude statements she made to police who questioned her without first advising her of her rights under Miranda v. Arizona (1966) 384 U.S. 436 (Miranda). Assuming without deciding that the trial court erred in admitting Cooper’s statements, we conclude the error was harmless. Accordingly, we affirm the judgment.

II. FACTUAL AND PROCEDURAL BACKGROUND

A. Factual Background

Around 9:00 p.m. on January 20, 2024, a courtesy clerk at the Vons store in La Mesa saw a woman, later identified as Cooper, put a bottle of alcohol in her backpack. The clerk radioed his observations to the store supervisor. The supervisor responded to Cooper’s aisle and saw the top of a bottle sticking out of the top of her backpack. Concerned that Cooper was shoplifting, the supervisor approached Cooper and asked if she needed assistance. Cooper ignored the supervisor, walked around the checkout area, and headed toward the exit without paying. A Vons security guard followed Cooper. He saw the top of a liquor bottle sticking out the top of Cooper’s backpack. The security guard recalled noticing the backpack was empty when Cooper entered the store. The guard introduced himself as a Vons security guard and instructed Cooper to pay for the merchandise she took. Cooper kept going. The guard followed her outside and confronted her, grabbing at the protruding liquor bottle in her

backpack.1 Cooper “started being feisty,” telling the guard, “You can’t stop me” and “leave me alone.” Cooper swung a fanny-pack at the guard and it (or Cooper’s hand) hit him in the face. She then fell to the ground and kicked the guard’s legs. A security guard who patrolled the entire shopping center intervened to help the Vons agent. Cooper kicked the shopping center guard and ripped his vest. The backpack fell off Cooper, so the Vons guard picked it up and took it to the supervisor at the customer service counter inside the store. The Vons guard and supervisor emptied Cooper’s backpack, which contained a bottle of whiskey and other groceries. Cooper reentered the store acting “erratically” and requested her backpack. Cooper reached for the backpack and the store’s “scan gun” and kicked the security guards. To protect the scan gun, the employees pushed Cooper’s backpack and its contents toward her and told her to leave. The guards coaxed Cooper toward the exit, but instead she went deeper into the store, kicking the shopping center guard along the way. The Vons agent tried to use Cooper’s backpack to lure her outside. When Cooper kicked the supervisor, the shopping center guard picked up Cooper and took her outside. Cooper flailed her legs; scratched and spit on the guard and hit him with her fanny-pack; and hit a customer who was entering the store. The supervisor called 911 and reported that Cooper was “stealing alcohol” and attacking the security personnel. Several police officers responded.

1 Defense counsel cross-examined the supervisor and guard about store policy regarding physically contacting suspected shoplifters. La Mesa Police Department Officer Rafael Gonzalez was one of the responding officers. Footage recorded by his body-worn camera was played for the jury. As we discuss in greater detail below, Cooper admitted to Officer Gonzalez that she was attempting to steal liquor from the store. The Vons supervisor scanned all the items in Cooper’s backpack into Vons’s system and determined that some of the items were from Vons and others were not. The value of the Vons items was about $71.

B. Procedural Background

The People charged Cooper with one count of robbery.2 (Pen. Code, § 211.) After deliberating for about 38 minutes, the jury returned a guilty verdict. The trial court placed Cooper on two years’ formal probation and stayed a 180-day custodial term pending Cooper’s successful completion of a residential substance abuse treatment program.

III. DISCUSSION

Cooper contends the trial court erred by admitting her statements to Officer Gonzalez because the questioning constituted custodial interrogation and Officer Gonzalez had not Mirandized Cooper before questioning her. Assuming without deciding that Miranda error occurred, we conclude allowing the jury to hear Cooper’s statements was harmless.

2 (See People v. Estes (1983) 147 Cal.App.3d 23, 28 [“Whether defendant used force to gain original possession of the property or to resist attempts to retake the stolen property, force was applied against the guard in furtherance of the robbery and can properly be used to sustain the conviction”].) A. Background

The People’s first trial witnesses were the courtesy clerk, store supervisor, Vons security guard, and shopping center security guard. These witnesses testified about the incident as summarized above. After these witnesses testified, Cooper moved to exclude the statements she made to Officer Gonzalez. Although the trial court was concerned that the defense “wait[ed] so long to file” the motion, the court considered it. The court watched body-worn-camera footage from Officer Gonzalez and another responding officer. The footage showed three officers follow Cooper on foot as she walked away from them. One officer told Cooper to stop and sit down, and she complied. As the officers reached for Cooper’s hands to handcuff her, she resisted and told them to stop. The officer repeatedly explained that Cooper was not under arrest and was only being detained. The officers eventually handcuffed Cooper and patted her down for weapons. During this process, the officers again informed Cooper that she was not under arrest and was only being detained. Cooper volunteered, “They took my sh[**]. They took my stuff.” One of the officers responded, “You’re just detained right now, we’re going to figure everything out.” Two of the officers walked away to speak with Vons employees, while Officer Gonzalez stayed with Cooper. Officer Gonzalez asked Cooper for her name and whether she had identification. Cooper responded, “No, they took it all.” She provided her name and date of birth. Another officer brought a backpack from nearby and asked Cooper if it was hers; she said it was. As Officer Gonzalez radioed dispatch about Cooper’s biographical information, Cooper continued trying to talk to him.
