Elderly couple found dead after carbon monoxide alarm sounded in Maryland home

Investigators say a detector was activated before family members discovered the couple inside their Boyds residence.

BOYDS, Md. — An elderly Montgomery County couple was found dead inside their home after what investigators believe was a carbon monoxide incident that began with an alarm sounding inside the residence, according to police.

The Montgomery County Department of Police said 91-year-old Ceferino Jarin and 89-year-old Elizabeth Jarin were found unresponsive inside their home in the 12700 block of Fernberry Lane on Saturday, June 27.

According to investigators, Elizabeth Jarin told family members earlier that day she believed a smoke alarm was sounding and that her husband was unable to reach it to turn it off. Detectives later determined the alarm was a carbon monoxide detector.

Family members went to the home after a home health aide was unable to make contact with the couple. When relatives arrived, they found both residents unresponsive and called 911 at about 3:23 p.m.

Montgomery County Fire and Rescue Service personnel and Fifth District police officers responded to the home and pronounced Ceferino and Elizabeth Jarin dead at the scene.

Fire and Rescue personnel detected carbon monoxide levels of approximately 2,000 parts per million on the home’s main level. Investigators also found a vehicle with its engine running inside the attached garage.

Detectives with the Montgomery County Police Major Crimes Division responded to investigate.

Police said the deaths do not appear to be suspicious. The investigation remains ongoing.
