Judge Anthony R. Villalobos

Judge Anthony R. Villalobos serves on the Riverside County Superior Court, appointed by Governor Jerry Brown in 2015. His documented case history reflects a consistent focus on serious felony matters, including homicide, manslaughter, sexual abuse, and capital cases, primarily in the Coachella Valley region. His tenure spans over a decade of handling the most consequential criminal proceedings in Riverside County. The available case data points to a judge who applies deliberate evidentiary standards in criminal proceedings. In a 2016 street racing death trial, Judge Villalobos excluded drug and speeding ticket evidence, demonstrating a willingness to limit prior conduct evidence when its admissibility is legally contested. His 2018 ruling that an accused cop killer was mentally fit reflects engagement with competency determinations in high-profile matters. These documented rulings indicate a judge who takes evidentiary gatekeeping seriously in serious felony cases. Given the volume and gravity of cases he has presided over — including a 15-years-to-life sentence in a 2017 matricide case and a 2017 voluntary manslaughter matter — Judge Villalobos has substantial experience with the full range of criminal sentencing, from plea dispositions to life terms. Attorneys appearing before him in criminal matters should expect a judge with deep familiarity with serious felony procedure and sentencing frameworks.

Attorneys appearing before Judge Villalobos in criminal matters should prioritize rigorous evidentiary preparation. His documented exclusion of prior conduct evidence — specifically drug history and prior speeding tickets in the 2016 street racing case — signals that he scrutinizes the relevance and prejudicial impact of such evidence. Defense attorneys should file targeted motions in limine to exclude prior bad acts or uncharged conduct, while prosecutors should be prepared to articulate a clear, legally grounded basis for admissibility beyond propensity. Given his experience with competency and mental fitness determinations, attorneys in cases involving defendants with mental health histories should be prepared to present thorough psychiatric documentation and expert testimony. His 2018 ruling on mental fitness in a cop killer case demonstrates that he engages substantively with these determinations rather than treating them as procedural formalities. For sentencing proceedings, attorneys should recognize that Judge Villalobos has imposed significant sentences, including 15 years to life, in serious felony matters. Mitigation packages in life-sentence-eligible cases should be comprehensive and submitted well in advance of the sentencing hearing. Aggravation arguments from prosecutors should be grounded in the specific facts of the case and supported by the record.
