A dog was found dead and a resident suffered smoke inhalation during a house fire in Marengo Monday evening, fire officials said.

The Marengo Fire and Rescue Districts responded around 6:32 p.m. Monday to the 600 block of West Grant Highway for a report of a structure fire.

Marengo Fire & Rescue Districts Communication Specialist Alex Vucha said firefighters arrived within three minutes to find light smoke showing from a two-story duplex.

Crews quickly made entry into the home and found heavy smoke throughout.

The fire was isolated to the dining room of the first-floor residential unit, Vucha said.

The entire structure was deemed uninhabitable until repairs and cleaning can be completed due to the smoke damage.

A total of three occupants were temporarily displaced.

The fire is not believed to be suspicious in nature.

Vucha said an unattended candle is being investigated as the cause of the fire but the incident remains under investigation.

Both units were unoccupied when the fire began. The fire was reported by a tenant when they arrived home.

Firefighters found a family dog deceased inside the residence, Vucha said.

A resident was evaluated for smoke inhalation but did not require transport to the hospital. No one else was injured.
