A man has died in a house fire on the east side Tuesday morning after a neighbor tried to save him.

Fire crews responded to the fire at 8:53 a.m. at the 200 block of Belmont near North New Braunfels and Commerce Street. A neighbor tried to force his way into the home, but wasn't able to save the man's life.

The man, believed to be in his 50s, was the only person in the home.

One of the neighbors noticed smoke coming from the house and tried to get into the house, but burglar bars on the windows made it difficult. He was able to pull his neighbor out of the flames, but the man was dead by the time first responders arrived.

The cause of the fire is still under investigation, but the fire appears to have started in the kitchen.

The San Antonio Fire Department has been canvassing the neighborhood with smoke detectors and reminding residents to be careful with the cold temperatures this week.

“It's very important during this time of the year that the citizens don't use unorthodox ways to heat themselves,” SAFD Chief Charles Hood said. “If you are using space heaters, make sure that space heater is pulled away at least 3 feet away from any type of materials.”

Officials advise residents to not use kitchen ovens or stoves to heat their homes. It is also recommended that every home has a working smoke detector. If you need a smoke detector, you can call 311 to receive one.
