Charges are expected soon in the case of the dead hogs found last week in the Raccoon River in northwest Iowa. The Sac County attorney has announced plans to file charges early next week against the person believed to be responsible for dumping more than 30 dead hogs in the Raccoon River.

Department of Natural Resources investigators and Sac County Sheriff’s deputies say they have traced the origin of the hogs to a farrowing operation in Indiana. They say the hogs were being transported to a confinement feeding operation in Iowa, when 143 of the animals died. At least 31 of those hogs were dumped in the river, and later discovered by canoeists.

Individuals, if convicted in the case, could face fines or time in prison, or both for improper disposal of dead animals and causing water pollution.
