An Arizona gunman’s rampage that resulted in a U.S. congresswoman being shot has inspired a storyline in an upcoming episode of NBC’s Law & Order: LA.

The primetime drama started filming today an episode where a female state senator is gunned down in a public setting. The storyline echoes an incident last January when a gunman shot U.S. Rep. Gabrielle Giffords in head and killed a federal judge, among five other victims, at a public meet-and-greet outside a suburban Tucson grocery store.

Stories taken from real-life headlines have been a part of L&O’s brand for decades and a rep for L&O: LA emphasized that the show is fiction.

Tonight’s episode of LOLA is loosely based on another real-life crime tragedy — the murder of publicist and power player Ronni Chasen. In the LOLA version, the character is a Hollywood stylist and the show airs at 10 p.m.
