The mother of an Indiana University student who vanished more than two weeks ago says the family has set up post office box for anonymous tips.
Charlene Spierer said during a Wednesday news conference she was disappointed that more of 20-year-old Lauren Spierer's friends hadn't contacted police with information.
She says the family set up the post office box to protect anyone who was reluctant to come forward.
Police reported no new developments in finding the Greenburgh, N.Y., woman.
Bloomington police Capt. Joe Qualters says investigators will now compare notes and determine what steps to take next after interviewing a second round of witnesses. He says searches in Bloomington and the surrounding southern Indiana countryside will continue.
