What's Up, Chuck?

"Upstairs" John fears that Dolores' downward spiral might have ended tragically, and when Sipowicz and Sorenson investigate her disappearance, they face off with a high profile attorney from Sipowicz's past. Elsewhere, a dysfunctional family leads Greg and James into a bizarre murder case, and Jill and Diane get an even weirder case that could be a murder case, a kidnapping case, or no case at all.
