Emergency workers speculate each of the victims climbed into the pit in a frantic attempt to rescue the others. "It was a domino effect with one person going in, the second person going after them," Sheriff Don Farley said.
Farley identified the victims as Scott Showalter, 33; his wife, Phyillis, 34; their children, Shayla, 11, and Christina, 9; and Amous Stoltzfus, 24, who worked at the Showalter's dairy farm.
The accident began Monday evening when Scott Showalter tried to transfer manure from one small pit to a larger one.
At some point, the pipe that was transferring the manure became clogged, and Scott Showalter climbed in the pit to fix the blockage, Farley said. He apparently was overcome by methane gas, which is a byproduct of the liquefied manure, Farley said.
Emergency workers believe Stoltzfus climbed into the pit in an attempt to rescue Showalter. When the two men did not come out, Phyillis Showalter and then the couple's two daughters apparently made their way in, all succumbing to the deadly gas.

More than 5.8 million people voted for Nicholas Maduro at the presidential election in Venezuela. This is more than a quarter of registered voters. Why did those people vote for the man, who, as Western media write, took Venezuela to the brink of collapse?
It has long been understood that the West has been trying to subject Russian borders to total control. We have not seen such activity even during the Cold War
