UPDATE: Search for missing infant

A few curiosities are developing in the case of a five-day-old boy, who disappeared Thursday morning from a Town of Beloit home.  Police Chief Steve Kopp says about 40-officers, including detectives and agents have been identifying, locating, and interviewing family members, friends, and others who may have had contact with Kayden Powell.  His 18-year-old mother, Brianna Marshall called 9-1-1 Thursday morning about 4:30 to report he was missing from the bassinette in the room she was sleeping at a relatives home on East Homeland Court.    Kopp says they were staying there, because someone at their Beloit home was sick, and they didn't want their newborn to be at risk.  Among the people police have talked to includes an aunt, who was visiting the home where the baby disappeared, and left at 1:30 in the morning.  Police caught up with her in Iowa, and held her on a warrant from Texas. Police say they've made no arrests, and haven't named any suspects, as of a 6:00 p.m. news conference Thursday.  Kopp says the home has been treated as a crime scene, and a news conference is expected later Friday morning.
