HENDERSON — Authorities are investigating a barn fire that left about 250 hogs dead in Henderson.

Henderson Fire Chief Brandon Phillips says the fire was reported early Sunday by a motorist.

The barn housed about 400 hogs, but crews were able to cut holes in the walls to let about 150 hogs escape.

Phillips says the rescued hogs were moved to another barn in Renville.

Crews were at the scene about four hours. Fire departments from Le Sueur, Arlington and Belle Plaine assisted.

The fire is under investigation, but Phillips says an electrical wiring problem might have been the cause.
