MOTIVE - 'Crimes of Passion' - When a teenage girl is killed in a hit-and-run accident, first clues point Detectives Flynn and Vega toward the girl's disgruntled ex-boyfriend. Passion is a strong enough motive for murder, but Angie believes the boyfriend is innocent and begins to unravel a connection between the victim and an eminent prosecutor in the midst of a mayoral campaign. It turns out that passion may well be the motive, and the underpinning of a secret double life, on 'Motive,' THURSDAY, MAY 23 (9:00-10:01 p.m., ET) on the ABC Television Network.
