What Happened

On the evening of June 24, 2020, 51-year-old Jose De Jesus Mendez Rios was in the midst of a severe mental health crisis in his Richmond, California, home. According to bodycam footage released by the Richmond Police Department, Mendez Rios was holding knives to his own neck, clearly distressed and non-compliant with officers’ commands. For nearly 30 minutes, officers engaged in what they later described as de-escalation efforts, though their actions—shouting commands, deploying less-lethal munitions, and surrounding the home—appeared to escalate the tension rather than calm it.

The standoff ended in tragedy when officers opened fire, striking Mendez Rios multiple times. The Contra Costa County District Attorney’s Office, led by then-DA Diana Becton, conducted a review of the incident and ruled in February 2021 that the shooting was justified under California law. The DA’s report cited Mendez Rios’s refusal to drop the knives and the perceived threat to officers as justification for the use of deadly force. However, the family of Mendez Rios vehemently disputed this conclusion, arguing that the officers failed to employ proper crisis intervention techniques and instead resorted to lethal force prematurely.

Key Players

District Attorney
Diana Becton
Conducted the review of the shooting and ruled it justified, despite evidence of Mendez Rios’s mental health crisis and the family’s claims of excessive force. Her office’s report did not hold any officers accountable for the killing.
Richmond Police Officers (Anonymous)
Anonymous
Responded to the scene and engaged in a 30-minute standoff with Mendez Rios. Despite his clear mental health crisis, officers failed to de-escalate the situation effectively, instead deploying less-lethal munitions and ultimately using deadly force. No officers were disciplined or charged.
Richmond Police Chief
Bisa French
Defended the officers’ actions in public statements, claiming they followed protocol. French’s department has faced repeated criticism for its handling of mental health crises, yet no systemic changes have been implemented under her leadership.

Outcome

The killing of Jose De Jesus Mendez Rios resulted in no accountability for the officers involved or the Richmond Police Department. Contra Costa County DA Diana Becton’s office ruled the shooting justified, echoing a pattern of prosecutorial deference to law enforcement in cases involving mental health crises. The family’s wrongful death lawsuit, filed in June 2021, remains unresolved as of 2024, with the city and police department fighting the claims in court.

The Richmond Police Department has faced no meaningful consequences for its handling of the incident. Despite public outcry and calls for reform, the department continues to lack robust crisis intervention training, and officers involved in the shooting remain on active duty. The case has become a stark example of how California’s legal system fails to protect vulnerable individuals in mental health crises, prioritizing police impunity over justice.

Why This Matters

The killing of Jose De Jesus Mendez Rios is a tragic illustration of the systemic failures in California’s approach to mental health crises. Instead of receiving compassionate intervention, Mendez Rios was met with lethal force—a outcome that reflects a broader pattern of police violence against individuals with mental illness. Studies show that people with untreated mental illness are 16 times more likely to be killed by law enforcement, yet California continues to rely on armed officers as first responders in these situations.

This case also highlights the complicity of prosecutors like Diana Becton, who routinely rubber-stamp police shootings as justified, even when evidence suggests excessive force. The lack of accountability in Mendez Rios’s death sends a dangerous message: that officers face no consequences for failing to de-escalate or for using deadly force against vulnerable individuals. Until California enacts meaningful reforms—such as mandatory crisis intervention training and independent oversight of police shootings—tragedies like this will continue to occur.
