NG made up the WYD. According to BD it was WRUD.
JEAN CASAREZ, "IN SESSION": You know something interesting, Billie Dunn said last night that there had been a call made on that Monday, December 27th, to Hailey`s little friend about 2:00 in the afternoon. Well, now we have confirmation that a call was made from Billie Dunn`s cell phone to this little girl. We still don`t know who made it, but it corroborates what Billie Dunn said last night.
GRACE: Well, wait a minute. Now, Jean, what about this mystery text they`re saying they`re investigating, a text that says -- it was in slang - - What are you doing?
Like, "WYD," what are you doing. Do we believe that Hailey actually sent that to [MB] (ph), the little friend, or are police wondering could somebody else have sent that? And what time was that text?
CASAREZ: They have to be wondering that, 2
`clock 00 in the afternoon. And what are you doing? If you`re going to go spend the night there, wouldn`t you say, I`ll see you soon? I`m almost there? And there was never a response from the little girlfriend.
GRACE: Now, how do we know for sure that that call you were talking about was made, Jean Casarez?
CASAREZ: We know because it was on the cell phone. There were search warrants executed on that cell phone. Law enforcement have that phone, and they found it.
GRACE: Also joining us tonight, Alexis Weed. Alexis, what more do you know?
ALEXIS WEED, NANCY GRACE PRODUCER: Billie Dunn is telling us that she saw herself that text, that she saw it before police seized her phone, which they still have. Her phone has not been returned. So she`s saying that she saw it with her own eyes, that
"WRUD," what are you doing, to the friend.
