A girl had been missing for about a week when his coworker asked the super to open up the apartment. The flat was full of packages so the girl might have decided to move on. Her parents told the police she had just lost her job as senator assistant, so she was willing to come home till she managed to find a new job. Briscoe and Green start digging in her personal life, realizing she used to hang out with older men since high school and when her dead body was found buried in the wood, they narrow down the suspects to middle aged men close to her. A state official and family friend is the prime suspect, mainly because he used to cheat on his wife (who lived upstate together with three kids): when it's time to cut off the on side relationships he used to call a bartender (Timothy Wheeler) to clean up the mess. A 10 gran cash withdrawal from a bank account could convict the defendant, but you have to wait till the very end to realize who the real perp was...
