Rainn Peterson back with great grandparents as investigation into disappearance continues

YOUNGSTOWN, Ohio - Two-year-old Rainn Peterson who went missing for two days last week is now home with her great grandparents who have temporary custody of the child.
But the investigation into what led to her disappearance is far from over according to the Trumbull County Sheriff.
There is plenty of talk and plenty of questions surrounding the two day disappearance of Rainn Peterson from her great grandparents North Bloomfield home.
Some that even stirs suspicion with law enforcement, about the condition of the child when she was found.
Sheriff Tom Altiere was interviewed by Lindsay McCoy on WFMJ Weekend Today.
"Did you say she did not have a dirty diaper? No she did not have a dirty diaper, it was a wet diaper. Does that raise questions for you? Absolutely," Sheriff Altiere said.
So what is law enforcement looking into in terms of this investigation moving forward?
"Well we're looking for results coming back with her clothing to see if there's any oher DNA on there. Anything else that we can find just looking at her clothing," Sheriff Altiere said.
And what about those lie detector tests taken during the most critical hours of the search for little Rainn Peterson?
"There's still some questions, but you know that it was a high anxiety time for these people. You could say one didn't pass, but really they didn't fail, so maybe at a later date when everyone calms down we can go back to that person and say look we want to eliminate you from this investigation. Would that include the mother Brandi Peterson, does she have to have another one (lie detector test)? No she doesn't. So nothing suspicious surrounding her? We could find no fould play on her behalf," Sheriff Altiere said.
The Sheriff also says the great grandparents were never on the radar, that's why they have temporary custody of Rainn now.
As for why they did not allow volunteers early on in the search? Altiere says they were in rescue mode, and they wanted to preserve any evidence. Unsure of exactly what they were dealing with at the time.
