This week in 'Crime Scene,' former TV police reporter and Baltimore City Police spokesman Matt Jablow brings you a case that has gone unsolved for nearly 45 years.

In November 1969, a 26-year-old nun, Catherine Cesnik, disappeared after leaving her Southwest Baltimore apartment to go shopping. Two months later, her beaten body was found in a frozen field in Baltimore County.

No suspect was named in the original investigation, but in 1994, sensational allegations arose that re-opened the case. However, those leads ultimately went cold and Sister Catherine Cesnik's murder remains unsolved.
