UPDATE: One person died in a Jefferson County home explosion, according police.
The Jefferson County Sheriff's Office says the victim was inside the home when it exploded. One other person lived at the house and was not home at the time.
The cause of the explosion is still unknown, but authorities said it appears similar to that of a natural gas explosion.
A square mile area was evacuated before gas was turned off to the home and neighborhood. Several homes nearby sustained structural damage.
One man who lives nearby said the explosion sounded like a bomb went off.
"It exploded and it shook our house which is about two to three blocks from here, and it just shook everything in our house. The sound was unbelievable, loud. It was like a bomb, like a giant bomb. I've never heard anything like that before," Dave Matysik told WISN-TV.
