Posted March 01, 2019 08:16:23 Ben Zelle, who has worked at the Dallas Fire Department for 15 years, was killed in a fire.

Zelle was a firefighter for the department since 1993.

He was the second Dallas firefighter to die in the line of duty this year.

His death comes on the heels of a deadly fire that claimed the life of another firefighter.

The Dallas Fire Rescue Service said in a news release Monday that Zelle was one of three firefighters on duty that night in an apartment building in the city’s southwest suburb of Plano.

A source told NBC News the building where the fire took place had no sprinklers or smoke detectors.

The fire also took place in a building in Plano’s northwest neighborhood.

Fire officials said no one was inside the building at the time.
