Attorneys representing the city of San Marino and officers Carlos Bonilla and Alejandro Sandoval submitted new court documents to Judge Jared D. Moses in Pasadena Superior Court. The defense is requesting that Dr. Marc A. Cohen conduct independent psychiatric examinations of Diana Mancillas and her daughter, Gabriana Gutierrez. These evaluations must be completed no later than January 31, 2027, at a Beverly Hills office. The interviews could last up to eight hours and will be recorded via audio and video platforms.
The lawsuit, originally brought in May 2025, outlines severe claims including false arrest, imprisonment, sexual battery, negligence, intentional infliction of emotional distress, and civil rights violations. According to the complaint, a man called 911 on May 5, 2023, reporting he was following a suspected stolen 2013 Kia Optima. Although the caller admitted the license plate did not match his vehicle, he still requested police intervention.
Mancillas had already parked her car when the incident occurred. The suit states that despite lacking reasonable suspicion or probable cause, SMPD officers arrived and pointed their weapons at the women. They were ordered out of the vehicle with hands raised and walked backward in front of bystanders before being handcuffed. Gutierrez, who was 19 at the time, alleges she was moved to a less visible area next to a patrol car where she was groped on her thighs and breast. The touching is described in the filing as offensive, non-consensual, and a source of extreme humiliation and fear.
The entire encounter, from the unjustified high-risk stop to the unlawful groping of Gabriana, constituted unreasonable and excessive force under the circumstances, the lawsuit reads.
In their counter-motion, the city and officer attorneys argue that the lawsuit should be dismissed entirely. They maintain that the officers were responding to a legitimate 911 report regarding a potentially stolen vehicle. The defense describes the interaction as cordial and asserts that the plaintiffs merely experienced inconvenience and disagreement with police procedure. They contend that uncontroverted evidence shows the officers acted appropriately while investigating a possible crime.
This legal battle unfolds within San Marino, a city in Los Angeles County known for its tight-knit community and reliance on local law enforcement for public safety. Incidents involving high-risk stops and allegations of misconduct often spark intense debate regarding police accountability and resident rights. The demand for psychological evaluations highlights how these cases frequently extend beyond immediate physical injuries, targeting long-term emotional well-being and public perception of law enforcement conduct.
Civil lawsuits against municipal police departments in California frequently navigate complex standards regarding qualified immunity and probable cause. Courts often weigh whether an officer's actions were objectively reasonable at the moment of the encounter against subsequent claims of harassment or excessive force. Previous rulings in the region have emphasized that mistaken identity reports do not automatically justify militarized responses if basic verification steps are overlooked.
The ongoing proceedings will determine whether the psychological assessments proceed and whether the court finds sufficient grounds for the case to move forward. Residents and legal observers in Los Angeles County will watch closely as this matter tests the boundaries of police authority and civil liability.
