Bryan Kohberger Pleads Guilty

After a surprise plea deal agreement, Bryan Kohberger appeared in court on Tuesday and admitted to killing four University of Idaho students: Madison Mogen, Kaylee Goncalves, Xana Kernodle and Ethan Chapin. 48 Hours correspondent Peter Van Sant and CBS News legal analyst Mary Fulginiti explain the significance of this latest court hearing and how it has affected the families of the victims. While some support the deal, others feel justice hasn't been served. As for motive, this remains a mystery.
