"FILE - This Feb. 6, 2013 file photo released by Starpix shows TV personality Katie Couric at the premiere of ""Makers: Women Who Make America"" at Alice Tully Hall at Licoln Center in New York. New York City police said Thursday, Feb. 14, 2013, they had been called to Couric's Manhattan home several times recently because of 911 calls traced to a phone listed there. The 911 operator hears only static, but police are compelled to answer each call. The calls come on Tuesdays at 2 a.m., as Couric told an audience at her talk show's taping this week. Police say they are investigating whether something's wrong with her phone or if Couric is the victim of a high-tech prankster.  (AP Photo/Starpix, Marion Curtis)"
