Kardashian took the luggage home with him.
I know there was testimony that luggage was seen by a garbage pail, but I always thought that Kardashian took the luggage. That's why Cochran added Kardashian to OJ's legal team, so that the luggage in Kardashian's possession would be protected by attorney-client priviledge.
I recall a discussion at the time that Kardashian was a family lawyer, not a criminal lawyer, so it was strange for him to be added to the legal team. The only logical reason that I concluded was that it was to protect what Kardashian knew.
