CO causes death of two elderly adults in apartment building

Carbon Monoxide Poisoning Suspected in the Deaths of two Santa Rosa Residents

On Tues., Nov. 7, 2023, at approximately 9:34 a.m., the Santa Rosa Fire and Police Departments were dispatched to 2705 Range Ave. for a medical incident involving two elderly adults down on the floor in an apartment and possibly deceased. The responding fire crew arrived and was met outside a first-floor apartment of a two-story multi-unit apartment complex by a maintenance representative. The representative advised that he entered the apartment to complete routine maintenance, found them and called 911.

The City of Santa Rosa Fire Dept. crew entered the apartment and located the two subjects. While checking for signs of life, it was determined that the subjects may have been exposed to carbon monoxide. Fire crews exited the residence, donned self-contained breathing apparatus, and re-entered the residence with specialized air monitoring equipment. The monitor confirmed high levels of carbon monoxide present. During the re-entry and while completing a thorough search of the residence, Fire crews located a dog inside a bedroom. The dog was still awake and alert, removed from the residence and turned over to Sonoma County’s Animal Control.

The Santa Rosa Police Dept. assisted the Fire crews in checking the remaining eleven apartments in the building for residents and the presence of carbon monoxide. Five residents from various apartments were located and evacuated from the building. All other apartments were clear of any carbon monoxide, and none of the additional residents had any medical complaints.

Santa Rosa Fire crews assisted the Santa Rosa Police Dept. with the investigation of the incident. Based on the preliminary investigation, it is believed that the deaths were the result of carbon monoxide poisoning from a natural gas fueled appliance. The official cause of death is pending the completion of victim autopsies by the Sonoma County Coroner’s Office. The investigation is ongoing. Santa Rosa Police and Fire were assisted by the Santa Rosa Building Division, AMR and PG&E.
