Dateline/Law & Order: CI Thursdays

When Corey Parker doesn’t show up for her waitressing shift, a co-worker goes to her apartment in Jacksonville Beach, Florida to check on her. What he finds triggers an investigation that would last almost seven years.

When the son and daughter of a wealthy businessman are found murdered in his apartment, Detectives Goren (Vincent D'Onofrio) and Eames (Kathryn Erbe) suspect the father's second wife (guest star Noelle Beck) -- but discover the key to the homicide may lie with two young nannies (guest stars Tammy Blanchard and Merritt Wever) with ties to the aggrieved family. However, the police probe could prove fruitless unless Goren can find more crucial information on the women's background and relationship.
