Three people have been found stabbed to death inside an Illinois beauty salon. A customer who arrived for a midday appointment found the bodies of the owner of Michael's Salon in Belleville, Illinois, and two elderly sisters who were customers. Police Chief Terry Delaney says it doesn't appear robbery was the motive. Police say they're looking for a "person of interest" they want to interview. Police are also searching for the owner's gold-colored sport utility vehicle. Bellville is near St. Louis.
