Fire kills 650 pigs in northwest Iowa
Northwest Iowa authorities haven't found any links between the fire deaths of several hundred pigs and the deaths of several hundred hogs after someone changed settings on a climate control system.
The fire was reported around 9:50 p.m. on Saturday at a confinement facility four miles southeast of Rock Valley. The Sioux City Journal says about 650 30-pound pigs were killed.
Authorities say an estimated 475 hogs died last week at a confinement facility five miles south of Rock Valley. The Sioux County Sheriff's Office says someone entered the building and tampered with the climate control system between 3 p.m. Tuesday and 1 p.m. Wednesday.
Sheriff's spokesman Nate Huizenga said Monday that the investigations are continuing, but "at this point it looks like the incidents are not related."
