A structure fire in the Lower Valley Saturday night was caused by a smoker's carelessness, El Paso fire officials said.
The fire along the 6200 block of Tampa Avenue started about 10:45 p.m. and affected a storage structure behind a home. Eight fire units and 22 firefighters responded to the incident.
Fire crews had the fire under control within 10 minutes and contained it to one of the rooms in the storage structure.
A cigarette ember fell into a cardboard box, catching the box on fire and then spreading, fire officials said.
No injuries were reported. The storage structure did sustain smoke damage but the main house was not affected.
Damages were estimated at $15,000.
