CSI: NY, Season 6

Mac:
(about Richard Lawson) If this guy's a successful real-estate agent, what's he doing breaking into Sam Harding's penthouse?

Stella:
Well, before he died, Harding set up a trust to take care of his home, keep it empty after his death. Nobody was allowed to go inside, not even the building's super or maintenance man.

Mac:
He wanted to hide the fact that he murdered Walter Jones and left him there to rot.

Stella:
His secret and Jones' body would've remained undiscovered, except this week the rule against perpetuities went into effect.

Mac:
That stops dead people from owning property forever.

Stella:
Right, which means the penthouse was just about to be put up for auction by the state.
