Investigators are trying to find out the cause of an explosion in a house in Detroit Thursday morning.
They're looking into the possibility that it was a gas leak.
It was powerful enough to blow out windows and wake neighbors up around 3:30am.
Some of the debris landed 30 yards away from the house.
The only reason the owners weren't home is that they were at the hospital where the husband was being treated for complications from surgery he had last week.
