Richmond, Utah — A man and four children were found dead inside a Utah home after carbon monoxide alarms reportedly sounded for hours, prompting neighbors to enter an adjoining apartment and alert authorities.
The Cache County Sheriff’s Office said deputies responded to an emergency at a triplex in an apartment complex in Richmond at approximately 12:15 p.m. local time on Saturday, October 10. Investigators found five people dead inside the residence, where officials reported dangerously high levels of carbon monoxide.
Authorities are continuing to investigate what happened, including whether the deaths were accidental or intentional.
Neighbors Heard Carbon Monoxide Alarms for Hours
According to the Cache County Sheriff’s Office, neighbors entered an adjoining apartment after carbon monoxide alarms had reportedly been sounding for an extended period.
When a neighbor entered the residence, they discovered an adult man dead in the garage, authorities said. First responders subsequently arrived and found four additional people dead inside the home.
Cache County Sheriff D. Chad Jensen told that a neighbor reported hearing the alarms beginning around 8 a.m. or 9 a.m., several hours before deputies arrived.
Jensen noted that the alarms were “not very loud,” according to the report. The circumstances surrounding the delay between the alarms sounding and the discovery of the victims remain unclear. Officials have not publicly established exactly when the carbon monoxide exposure began or how long the victims may have been exposed.
Who Were the Five People Found Dead?
The sheriff’s office identified the victims by their ages and genders. They included a 43-year-old man, a 16-year-old boy, a 12-year-old girl, an 11-year-old boy and a 5-year-old girl.
Authorities had not released their names in the initial report.
Sheriff Jensen said the deceased individuals were related, although officials have not publicly provided further details about their family relationships.
Investigators are awaiting additional findings to help establish what led to the deaths. The medical examiner’s examination is expected to play an important role in determining the circumstances of the incident.
“I think the majority of our answers will come when the medical examiner is done doing an examination,” Jensen said.
Carbon Monoxide Levels Exceeded Detection Equipment Limits
Officials reported extremely high carbon monoxide levels inside the apartment.
According to reports, Sheriff Jensen said the concentrations were so high that they exceeded the limits of the detection equipment used by emergency responders.
Carbon monoxide is a colorless, odorless gas that can become deadly when it accumulates indoors. Because people cannot detect it through smell or sight, functioning carbon monoxide alarms are an important warning system in homes and apartments.
The gas can be produced by fuel-burning appliances, heating systems, generators and other equipment that burns gasoline, natural gas, propane or other fuels. Poor ventilation or malfunctioning equipment can allow dangerous concentrations to build up.
Investigators have not established the source of the carbon monoxide in the Richmond residence.
Neighboring Apartments Evacuated After Discovery
The emergency response extended beyond the apartment where the five victims were found.
The sheriff’s office said deputies and fire personnel evacuated both adjoining apartments as a precaution. One adult man from a neighboring apartment was transported by ambulance to a local hospital for possible carbon monoxide exposure.
Authorities have not released further details about that man’s condition.
The evacuation underscores the danger carbon monoxide can pose in multi-unit residential buildings, where gas may potentially affect people beyond the location where it originates. Officials have not announced a final determination about the cause of the incident.
Investigation Continues as Officials Await Answers
The deaths remain under investigation by the Cache County Sheriff’s Office. Authorities are working to establish the circumstances surrounding the carbon monoxide exposure, and the medical examiner’s findings are expected to help answer key questions.
The U.S. Centers for Disease Control and Prevention estimates that approximately 400 Americans die each year from unintentional carbon monoxide poisoning.
Safety officials recommend installing carbon monoxide alarms near sleeping areas and on every level of a home, following manufacturer instructions, and checking that the devices work properly.
If a carbon monoxide alarm sounds, leave the building immediately, get into fresh air and call 911 from outside. Do not re-enter until emergency responders say it is safe.
