A foul odor coming from a northeast Miami-Dade apartment led police Tuesday to the body of an elderly woman and her unconscious husband.

A neighbor of 77-year old Wylene Floyd called the landlord Tuesday to report a bad smell coming from a nearby unit in Romont South, a building off of Northeast Second Avenue and 203rd Street.

The woman reportedly said the smell had been around for about 48 hours and had made people sick.

The landlord called a relative of the Floyds. When the relative went into the apartment through the back door, she found the body of her grandmother on the floor and Wylene’s husband, Bobby, passed out nearby.

Bobby Floyd was rushed to Jackson North Medical Center. Once he is stable he may be moved to a facility with a hyperbaric chamber in Palm Beach County.

Miami-Dade police are investigating the exact cause of death. However, a police spokesman said firefighters did detect carbon monoxide in the house.
