Must be dried fluid?

Original Story: The private investigator hired by the Deorr Kunz family said a cadaver dog scented blood or other bodily fluid on a piece of equipment while searching for the boy’s body. He said the evidence proves there was a death.
Philip R. Klein of Klein Investigations and Consulting spoke with reporter Chelsea Brentzel Wednesday. He wouldn’t say what the piece of equipment was or when the cadaver dogs found it.
“We believe it is important for the public to know that the cadaver dog did hit in three certain areas of the pieces of equipment which does indicate there was a death or there was some type of fluid, cerebral fluid, blood whatever it may be, that was in the location where the dog hit, and that we know there was a death,” said Klein.
Lemhi County sheriff’s office isn’t confirming what Klein is saying.

This seems to be at odds with Sheriff Bowerman's comments during the radio interview a couple of days ago. He said that the LE had shared none of their findings with Klein. It's unclear at what stage the dogs allegedly alerted to the truck but I would assume it must have been within the first few weeks after the disappearance.
Am I correct in remembering that it was said Vernal, Jessica & Deorr slept in the granddad's trailer on the first night?
