SOCHI, Russia (AP) — Nancy Kerrigan’s voice cracked and her eyes welled with tears. She had just watched a screening of NBC’s “Nancy & Tonya,” a one-hour special that is scheduled to air on Sunday, and the emotions stemming from the attack on her came rushing back.

Kerrigan has been reluctant to talk about rival Tonya Harding’s ex-husband hiring a hit squad to take her out before the 1994 Olympics in Lillehammer. She finally relented for a show that marks the 20-year anniversary of the incident, which thrust figure skating into the spotlight and spawned an international media frenzy.
