WATERLOO — Authorities say a man and a woman and two dogs were all found dead in a Waterloo home. Autopsies are planned for the two unidentified people found in the home Sunday morning. Authorities say they do not suspect foul play. Waterloo police and paramedics were called to the house shortly after 10 a.m. after an acquaintance arrived and found one of the two people unresponsive. Police say they’re investigating the possibility that the deaths are linked to a generator that was found inside the attached garage.
