DELPHI, Ind. --Family members of Abigail Williams and Liberty German are expected to make a statement to media for the first time on Thursday.

Neither family has spoken publicly since the girls went missing on February 13. It is unclear which family members will address the media.

The families of both girls toured the Delphi investigation headquarters last week.

While there, Abigail's grandparents made a stop at a board where the community can leave messages for investigators. Their message to police offered prayers and thanks:

Where are the police when you need them? I have uttered these words whenever a speeding or reckless driver nearly runs me or someone else off the road. Where are the police when you need them? They are here, in Delphi, with us. We pray for your protection, and we are forever grateful for your service Diane & Eric (Abbys grandparents)

Libby, 14, andAbby, 13, went missing on February 13 while hiking near the Monon High Bridge. Their bodies were found the next day less than a mile from where they were last seen alive.
