UPDATE: The fire marshal is still looking for answers as to what caused an explosion at this Jackson County home that left one man covered in burns.

The last thing the homeowner, Dan Miller, remembers is lighting a candle and then being blown out the back of the house.

The Jackson County Sheriff’s Department says Miller managed to run to the front of his house and into the road, where he was almost hit by a dump truck.

The driver of the truck hit the brakes so hard, you can still see the marks on the road.

The driver of that truck was the first to call 911.

The Miller’s wife and daughters were not home at the time of the accident.

Miller’s sister-in-law said they are accepting donations to help with the family’s recovery. You can make those donations at Clinton National Bank or Maquoketa State Bank to Jen Miller.

EARLIER VERSION: An explosion happened around 11:30 a.m. at a home in Jackson County near Preston.

It took three hours to bring the fire under control.

A man inside the home was burned and was flown to Iowa City.

His wife and children were not at home at the time.
