Shan Valencia Thomas v. Stanislaus County, Kyle Christianson, Eric Garcia, and Does 1-10, inclusive

No. 2:25-cv-02113 WBS CSK (E.D. Cal. Jan. 6, 2026) · United States District Court for the Eastern District of California · January 6, 2026 · No. No. 2:25-cv-02113 WBS CSK

Summary

The United States District Court for the Eastern District of California denied defendants’ motion to dismiss Shan Valencia Thomas’s First Amended Complaint arising from alleged police-dog and other excessive force during his arrest. The court held that Thomas’s nolo contendere plea to California Penal Code section 69 did not support dismissal under Heck v. Humphrey in light of King v. Villegas. The court also found that Thomas adequately pleaded municipal liability under Monell and supervisory liability under 42 U.S.C. § 1983.

Holdings

  1. At the pleading stage, Thomas's nolo contendere plea and the facts stipulated to in connection with it could not be relied on to establish that he committed a violation of California Penal Code § 69; therefore, there was no plausible basis to conclude that his excessive-force claim was barred by Heck.
  2. Thomas adequately pleaded a Monell claim because he alleged multiple sufficiently similar incidents in which Stanislaus County deputies allegedly used excessive force to punish subdued or restrained arrestees, together with allegations that the incidents occurred without discipline, investigation, or retraining.
  3. Thomas adequately stated a supervisory-liability claim because he alleged both a sufficient causal connection between the supervisors' wrongful conduct and the excessive-force violation and personal participation in the constitutional deprivation.

Questions Presented

  1. Whether Thomas's § 1983 excessive-force claim was barred by Heck v. Humphrey because he had entered a nolo contendere plea to violating California Penal Code § 69.
  2. Whether Thomas adequately pleaded a municipal-liability claim against Stanislaus County under a custom or policy theory.
  3. Whether Thomas adequately pleaded supervisory liability under § 1983 against the Supervisor and Officer Does.
