Town of Beloit police are searching for a missing four-day-old baby. Authorities say 18-year-old Brianna Marshall called 9-1-1 at 4:35 a.m. Thursday morning to report the child missing from a home at 836 E. Homeland Court. Town of Beloit Police Chief Steve Kopp says Marshall reported Kayden J. Powell missing from his bassinette in the room where she was sleeping. Kopp says the incident does not appear to be a child custody dispute. He says both the mother and father, 23-year-old Bruce Powell of Beloit were at the police station following the incident. The chief says investigators are working to locate and interview other people who were in the house Wednesday night. The FBI and Division of Criminal Investigation are assisting in the case.
