Adkins said at the beginning of the investigation he is innocent but we haven't heard much from him since.
He is talking about the disappearance on "Myspace". A few days ago he wrote an update that seems to be a message for Billie.
It says there is nothing more than I want than to be there for you... Don't lose hope, I love you Hailey and David.
Adkins also posted pictures of himself with Billie and Hailey that appear to be taken on Christmas day.
Adkins spoke to KTAB right after Hailey disappeared, but hasn't done any more interviews on the advice of his attorney.
