DES MOINES, Iowa (AP) — Authorities say an investigation into animal treatment at an Iowa state lawmaker’s hog farm found no evidence that animals were being abused despite video that a group posted that appeared to show otherwise. Two people with California-based Direct Action Everywhere entered a hog farm last spring owned by Republican Iowa state Sen. Ken Rozenboom. Mahaska County Sheriff Russell Van Renterghem says an investigation didn’t find any abuse. Rozenboom said he decided in December to lease the hog building to a different farmer. He has said veterinary records show the herd was being treated for a respiratory infection that contributed to the problems Direct Action Everywhere documented.

FORT DODGE, Iowa (AP) — Officials say two people suffered minor injuries in a fire that destroyed a Fort Dodge towing and auto business. Television station KCCI reports that the fire broke out Friday afternoon in Mid Iowa Towing. Firefighters arrived to find a large fire in the company’s shop area, with flames reaching the roof. The building is not served by the city and did not have fire hydrants, requiring the firefighters to use 500-gallon water tanks. Officials say the lack of water and presence of a large amount of flammable liquids, coupled with high winds, caused the fire to grow and spread quickly. Two of the business’ employees were treated for burns on their hands.
