In a surprise move, the Sago Mine disaster report will not be released Monday.
West Virginia's investigation is complete, but the families got the first look and they asked that the state not release the findings yet.
Instead, the families say they have more questions about it.
Last week, we got an early word that the state would blame a lightning strike for igniting the underground explosion.
Twelve coal miners died, but remember, the families were also told that eleven of those men were alive, only to learn later that night that they were dead.
A copy of the report obtained by The Associated Press says the methane gas explosion that caused the deaths was nearly five times more powerful than the underground seals were able to withstand.
The state also canceled a planned meeting today with the Board of Coal Mine Health and Safety.
