Medical Examiner Rules Trigg Kiser’s Death an Accidental Drowning

The report identifies anoxic brain injury from drowning as the official cause of death in a high-profile case reviewed by prosecutors who declined to bring charges.

Overview

  • The Maricopa County medical examiner’s report, obtained Tuesday, August 25, lists the cause of death as anoxic brain injury due to drowning and records the manner of death as an accident.
  • Trigg, 3, was pulled unconscious from his family’s backyard pool in May 2025, was hospitalized, and died six days later on May 18, 2025.
  • Chandler Police investigators said video and other evidence showed Trigg was in the backyard unsupervised for about nine minutes and in the water for roughly seven minutes before being rescued.
  • Investigators had recommended charging Brady Kiser but the Maricopa County Attorney’s Office later declined to press charges, saying there was no likelihood of conviction.
  • Emilie and Brady Kiser have publicly processed their grief with Emilie promoting pool-safety messages on social media and announcing in July that they are expecting a third child while limiting public details to protect privacy.
