>> he told my husband, he said -- and i thank him to this day for it -- he said, "i've got a number. and what you do with this number is your business. i've got to go to the radio and call this in." real quick like my husband copied it. >> even though it was nearly midnight, shauna's family mobilized their own search by following that phone number which led them to an abandoned construction site. >> there's nobody there. so my husband hangs up and he calls the man back, "where do you live?" the man gives us a different address. my husband keeps him on the phone to make sure he ain't lying to us. we pull up and it's an old man. he is probably like 80 years old. my husband gets out and said do you know shauna and [ bleep ]. he's like, "yeah she's my granddaughter."
