(KCRG) — A natural gas leak is to blame for a deadly home explosion in Waterloo, the fire department confirmed.

The Waterloo Fire Marshall made a preliminary determination that the natural gas leak came from inside the home, and that Mid-American equipment was not the cause of the gas leak. Investigators confirmed that Friday.

The explosion happened early Wednesday morning at a home on the corner of Sager Avenue and Sheerer Street.

One person died in the explosion. Officials have not released that person’s identity.

Anyone who suspects they smell gas should call 911 and their utilities’ provider.

 (KCRG) – Fire officials told TV9 there was one victim in a home explosion in Waterloo early Wednesday morning.

A TV9 crew saw what appears to have been a body pulled from the home. City officials have now confirmed that one person is dead.

Waterloo Fire Rescue said the explosion happened at a home on the corner of Sager Avenue and Sheerer Street.

Neighbors in the area told TV9 they heard what sounded like an explosion between 2 a.m. and 2:30 a.m.

Waterloo Fire Battalion Chief Ben Petersen told TV9 there was a large explosion, and after that crews found a small gas leak and a small fire.

A neighbor told TV9 the explosion blew their door open and broke a few items inside their house.
