With Law & Order andLaw & Order: Special Victims Unitheading into a major crossover event on April 17, the decision to bring a tragic end to one of Olivia Benson’s (Mariska Hargitay) most haunting cases couldn’t have been more emotionally charged. Audiences first met Maria in Season 7’s “911” — the episode that earned Hargitay her first Emmy.
