A pipe used to transfer manure from a small holding area to a larger manure pit became clogged Monday evening. And when dairy producer Scott Showalter climbed into the pit to unclog the pipe he was overcome by methane gas.
The invisible and deadly gas also killed four people who attempted a rescue -- an employee at the dairy, Showalter's wife Phyllis and two of their four daughters. The 103-cow dairy is located near Harrisonburg, Va.
According to an article in The Boston Globe, the local sheriff's department believes that after entering the small underground pit all were probably killed instantly by the gas.
