  NARRATIVE
  
  On Saturday, July 23, 2022, Vessel A was anchored on Brantley Lake, New Mexico. Vessel A is a wake boat with a swim platform at the stern. The engine was running and wind was light. A three-year-old female was swimming near the stern. At approximately 4:10 p.m., she swam up to the swim platform. After being at the swim platform for 10–15 seconds, she lost consciousness for about 15 seconds. She was immediately brought on board the vessel and taken to shore.
  
  When I arrived the child was being held by her mother. I noted the child looked drowsy. One of the responding firefighters told me they had been paged out for a seizure. I asked the child's parents if she has a history of seizures; they said no. According to statements made by the child's parents and first responders, the child began looking much better soon after being moved away from the exhaust. I noted all of the child's symptoms are consistent with carbon monoxide exposure.
  
  Next EMS arrived to assess the child. She was found to have elevated levels of carbon monoxide in her system (approximately 30%). I noted this seemed consistent with her symptoms. I also noted that young children are at higher risk of carbon monoxide poisoning due to their smaller size.
  
  I conducted a safety inspection of Vessel A and found all required safety equipment to be aboard. During my inspection I observed a carbon monoxide warning sticker was attached to the transom above the swim platform. The child was released to her parents without requiring hospital treatment. I cleared the scene at approximately 4:35 p.m.
  
  Based on my investigation, I believe this incident was caused by exposure to an accumulation of carbon monoxide from the exhaust of Vessel A.
