Seven women were found dead in northwest Indiana this weekend and police say a man in custody confessed to killing them. On Friday night, police discovered the strangled body of a 19-year-old woman at a Motel 6. As part of the investigation into her death, police served a warrant on a home and took a 43-year-old person of interest into custody. The man confessed to the killings, police said, and provided the locations of three bodies in Gary. The mayor of the nearby city of Hammond said on Facebook that some of the homicides go back 20 years.
