Yet another instance of an actor, having made an appearance as one character, being brought into the L&O series as a regular cast member. Milena Govich plays "Geneva" and went on to later join the series as Detective Nina Cassady.
This episode appears to be based on two separate cases/incidents:
- The 1998-2001 Sante and Kenneth Kimes case.
- The 1996-1998 Amy Grossberg/Brian Peterson case.
