Background

This civil rights action arises from the in-custody death of Joseph Morton. He was arrested by San Diego County Sheriff's deputies on May 11 for using a fake gun to rob a man sitting in a car with his children and was held at Vista Detention Facility. The order says the facts are disputed about how foreseeable his suicidality was and how effective his treatment by jail medical professionals was. He was found dead in his cell on May 17, a suicide by hanging. The defendants are the County, Liberty Healthcare (the contractor providing psychiatric care in County jails), a County employee, and three Liberty clinicians.

Before a January 25, 2027 trial, the parties filed motions in limine, motions to seal, supplemental trial briefs and a motion to quash a trial subpoena. After an October 23, 2026 hearing, the district judge issued this pretrial order, largely confirming tentative rulings. These are interlocutory trial-management rulings, not a final judgment, and several matters are expressly left open.

The Court’s Holding

On evidence, defendants may argue that Morton's suicide was a superseding cause and that others are generally responsible for his injuries. They may not argue that his mother or girlfriend are legally liable, offer expert testimony on how their care would have changed had they known of his jail-call statements, or use jail calls without first identifying excerpts. The robbery victim's testimony is excluded under Rule 403, but victim-impact portions of the police report are admissible. Defendants may mention that Critical Incident Review Board reports exist, but not their specific nature or that the Morton report found no wrongdoing. Photographs and videos of the noose and body are excluded under Rule 403, while his suicide notes are admissible.

The Lindsay Hayes report is inadmissible under Rule 37(c)(1) because its late disclosure was neither substantially justified nor harmless. The other external reports, including the grand jury, Disability Rights California, state auditor and medical examiner reports, are admissible. Defense experts may address the Sheriff's response to the Disability Rights California report, the 2017 national commission report, the medical examiner's report and the Disability Rights California report itself, but not timely disclosed reports absent from their expert reports. Dr. Canning would be barred as an expert for Rule 26 noncompliance but could testify as a lay witness, subject to a short supplemental brief. Dr. Metzner may opine that care was substandard and why, but not what defendants would have done with more information. Dr. Campbell may not opine on losses after certain family members' deaths.

The court held that its summary judgment order does not bar a collective-inaction Monell theory, so inadequate County policies or training may have caused multiple providers' inaction even if Sparks is not individually liable. It deferred whether Liberty defendants' conduct can support County liability and deferred comparative fault, noting apportionment is a legal question for the judge. It declined to enter judgment sua sponte on Liberty's direct-liability argument and bifurcated punitive damages. It ruled that plaintiffs may recover loss of earnings and that pre-death pain and suffering begins at the hanging. It unsealed the suicide note, family photographs, the note to his mother and Liberty's records, keeping jail-interior and body images sealed.

Key Takeaways

  • Defendants may press superseding cause but may not argue that the decedent's family members are legally liable.
  • Late disclosure cost the Lindsay Hayes report its admissibility, while the other external reports came in.
  • Experts are confined to their disclosed opinions and cannot say what defendants would have done differently.
  • The collective-inaction Monell theory survives, but County liability for Liberty providers and apportionment await the trial record.
  • Loss of earnings is recoverable, and pre-death pain and suffering is measured from the hanging.

Why It Matters

The order shows how a court may manage a jail-suicide trial: excluding graphic images under Rule 403 while admitting systemic evidence, enforcing disclosure rules, and allowing a collective-inaction municipal liability theory. It is a trial-court ruling that binds only this case.

Open items include a stipulated set of five to ten family photographs, Morton's substance-use, mental-health and criminal history, newly produced County policies, a verdict form avoiding duplicative recovery, and the subpoena of the former Sheriff. Renewed motions are due January 4, 2027 and responses January 6, with a joint status report on the subpoena and new jury instructions and verdict forms due December 14, 2026.
