75-year-old man killed in Naperville house fire

A 75-year-old man has been identified as the victim of a deadly house fire Tuesday in Naperville.

Krishna Emmadi, 75, was found dead after flames swept through the two-story house in the 3500 block of Redwing Court on Naperville’s far south side, authorities said.

An autopsy was performed on Wednesday. The final cause and manner of death will be determined after toxicology, autopsy and police investigation reports are completed.

Emergency crews responded to the blaze at about 3:15 p.m. When they arrived, heavy fire was showing from the second-story windows, and firefighters learned that someone was trapped on the second floor, according to a news release from the Naperville Fire Department.

The fire caused an interior stairway to collapse and holes in the floor on the second story. Flames also hampered firefighters’ efforts to enter through the windows, officials said.

One other person was injured in the fire, authorities said. No firefighters were injured.

The fire was under control by 4:33 p.m., according to the fire department.

The department says it issued a box alarm for more firefighting help due to “extreme cold and advanced fire.” The Aurora, Bolingbrook, Lisle-Woodridge, Fermilab, Oswego and Plainfield fire departments and districts assisted at the scene.

Damage was estimated at more than $800,000. City building officials deemed it uninhabitable. Five people lived in the house, according to the fire department.
