One person has died in a house fire on the east side Tuesday morning.

Fire officials say a neighbor called to report the fire at about 5:00 a.m. at a house in the 600 block of Hammond Street, near North New Braunfels and Rigsby Avenue.

Fire crews found the body of one person while battling the fire. Crews said the house was fully engulfed in flames when they arrived.

Neighbors told fire crews a 75-year-old man lives in the home.

Fire crews believe the fire started in the rear of the home, near a bedroom. They do not know what caused the fire.

The house is in front of Highland Park Elementary, and officials plan to close part of the street in front of the house during the investigation Tuesday morning.

This is a developing story and KENS 5 will update it as details come in.
