Darian Weiss

When a father driving with his two children is gunned down on the freeway, Megan is puzzled when she can't find a specific pattern to the suspect's behavior and goes to Charlie for some insight. But as additional freeway incidents occur, Don uncovers an unlikely clue that may lead them to the killer.

Senior agent Jack Malone (series star ANTHONY LaPAGLIA), a tough but compassionate, seasoned and astute professional, heads the New York Missing Persons Squad of the FBI. Jack and his dedicated team know too well that every second counts when someone vanishes. His squad includes Samantha Spade (series star POPPY MONTGOMERY), an agent whose blonde good looks belie a tough, complex approach to her work; Vivian Johnson (series star MARIANNE JEAN-BAPTISTE), a no-nonsense investigator with a special insight into victims' families; Danny Taylor (series star ENRIQUE MURCIANO), whose sensitivity is often covered up by his street smarts; straitlaced Martin Fitzgerald (series star ERIC CLOSE), whose recent brush with prescription drug addiction revealed a darker side of his straight-laced persona; and the team's newest member, Elena Delgado (series star ROSELYN SANCHEZ), a resourceful agent who previously worked in the NYPD vice unit.
