Deleting Multiple Sims

[rhodaloo]

I discovered last night that I have two copies of Tigger Broke and his wife.  Their son shows that he knows both couples. Best I can tell couple #2  are homeless.  Beside the fact this is probably the first clue the neighborhood is starting to implode, what would be the best way to clear them out of the game?  I've tried "fixall" but apparently that isn't the correct command to use.

Select the correct fambly, then try typing "nukeimposters".

Will try that and report back.
