TYLER, Texas (KETK) – A structure fire caused major damage to a home on the 700 block of Fannin Avenue in Tyler and displaced four families.

The call came in to authorities around 6:50 Friday morning near the intersection of Fannin Avenue and Berry Drive. Reporters on the scene said some water runoff is turned to ice on the roadway due to freezing temperatures.

“We’re actively dealing with ice on the ground from our hose lines and crews, and we’ve had a few firefighters fall, but no injuries, no injuries to the occupants,” Deputy Fire Marshal Randy Lee said while at the scene.

Lee said the fire has displaced four families, including at least two with children. The home was a two-story structure that housed four separate apartment units.

“We’re working with the Red Cross to get all four families hotel rooms and get them out of the cold,” Lee said.

Upon entry, firefighters searched both floors for any remaining occupants. All residents exited the structure safely, but firefighters found one pet dead on the upper floor.

The structure sustained significant damage throughout, according to Tyler Fire Marshal Paul Findley.

“Firefighters remained on the scene until approximately 10:30 a.m., and were able to salvage many of the Christmas gifts in the structure for those impacted by the blaze,” Findley said.

Officials said that based on a preliminary investigation, the cause could be electrical.

“The occupant that made the 911 phone call woke up to his breaker coming on and off, looked outside and could see the breaker box arcing, and an arc going up the side of the house,” Lee said.

Authorities had roads blocked in the area. Tyler Police, Tyler Fire and EMS responded to the scene. The fire department brought out five engines and one ladder company, along with a Battalion Chief and an Investigator.
