I'm confused: Party @ Tony's 7/4 - he's in NY

[krimekat]

Was the 7/4 party @ Tony's apartment where Casey "cooked" for friends the same party that Amy hosted for William Walters?

If Casey was @ Tony's apartment 7/4 she must've had a key and free access to complete privacy from 6/30 until his return 7/5.

Perhaps an obvious point I've been overlooking.

The party was on the 5th when he returned
