— Sue Quackenbush (D, 16:26) -

-
Around 6 pm on April 13, 2024, a photographer/blogger records Danielle walking along Lost Lane. Danielle’s car is stuck in mud nearby.
-
She asks for help but ultimately decides to walk toward the main road; the men filming her give her directions.
-
This is the last known sighting of Danielle.
“She tells them, what do I do? Which is asking for help, especially from a young girl who isn’t that trusting of people any longer.”
— Sue Quackenbush (D, 19:35) -
Authorities continue extensive but fruitless searches.

In March 2025, a searcher finds women’s underwear hanging from a tree near the area Danielle vanished. This item had not been found in earlier thorough searches.
-
Because police lacked resources for DNA tests, Sue and private investigator Jimmy Ramsey arrange independent DNA comparisons (result later inconclusive).
-
Ramsey believes both Scott and the male camper near Danielle may know more than they share.
-
Ramsey flags Scott’s two-week delay in reporting Danielle missing as highly suspicious.
“To not report her for, you know, let’s call it one day, maybe two days, but weeks out. I think that’s a big red flag for me.”
