An early-afternoon fire on Saturday damaged three buildings and left two families displaced in Denison. Officials with the Denison Fire Department received the call of a fire in the 100 block of Doolittle, just outside of North Texas Regional Airport — Perrin Field, shortly before 12:30 p.m.

Denison Battallion Chief Bruce Geilhausen said the incident is currently under investigation, but noted that nothing in initial reports heads to suspicion in the case. Units from Sherman, Pottsboro, Preston, Denison and NTRA responded to the call.

Vanessa O’Quinn, who lives at 152-B Doolittle, said she first noticed the blaze when smoke started to enter her duplex home from outside and set off her fire alarm. When she and her three children went outside, they found the adjoining carport ablaze.

“We went outside and the whole storage shed was on fire,” she said.

From there, the fire spread to the right side of the home, where it eventually burned through the roof, she said. O’Quinn said she and her children were all able to get outside safely, but she was uncertain of what could be salvaged. With the house currently unlivable, O’Quinn said she planned to stay with her sister in her apartment.

“You don’t expect this to happen to you,” she said. “You see it happen to other families, but you don’t expect it to happen so close to home.”

Geilhausen said the Red Cross has been alerted and is rendering assistance to the displaced family.

The second duplex unit was also damaged in the incident, but did not catch fire, Geilhausen said. The damage to this unit was primarily from water, smoke and heat, he said, adding that first responders were required to disconnect the electricity. As such, the building was currently unlivable, he said.

A woman on the scene said the owner of the second unit was her uncle, who was currently out of town.

Another house was also damaged and briefly caught fire, but Geilhausen said the damage was only to the exterior and the owners were able to return back into their home.
