OGDEN, Utah (ABC4) — The Ogden City Fire Department has confirmed four dogs were killed and eight people were displaced in a house fire on Friday morning after investigators believe a propane tank caught fire.

The department said they arrived at the house located on the 500 block of 6th Street on Sept. 1 around 11:15 a.m. Crews immediately got to work to extinguish the fire.

Prior to the authorities’ arrival, a neighbor assisted two teenage boys from the home after seeing smoke and flames. Firefighters later searched the home and did not find anyone else. Authorities were able to save one dog, however, the other four died in the fire.

Officials say eight people have been displaced due to the house fire and the Red Cross is currently assisting them. One firefighter also received treatment on the scene for a minor sprain.

It is estimated that the house sustained $400,000 of damage. The fire took 17 firefights, one ladder truck, and three engines to control. North View Fire assisted Ogden Fire during the incident.

The cause is currently under investigation, however, officials previously told ABC4 it was likely caused by a propane tank that caught fire.
