So far $50k has been taken from Kourtney at her Calabasas home, then $250k stolen worth of jewelry from Khloe's home, and now $4k has been taken in cash from Kourtney's Hampton rental, and they know it's an inside job since there's no sign of forced entry! They are now holding out from filming Keeping Up w/ The Kardashians until the thief is caught! They are set to start filming in October.
