Two people died in a structure fire in Rock Springs early Wednesday morning.

The Sweetwater County Coroner has identified 79-year-old Floyd Logan and 72-year-old Joyce Logan as the people who were found dead in a residential fire early Wednesday.

The coroner said the husband and wife both died of smoke inhalation.

FIrefighters from the Rock Springs Fire Department were dispatched to the fire shortly before 4:30 Wednesday morning. Crews found heavy smoke conditions when they arrived and were able to enter the home to extinguish the blaze.

Rock Springs Fire Chief Jim Wamsley said his office is working with the state fire marshal’s office to investigate the fire and determine its cause.
