When adults go missing, it's not unusual for LE to accept a missing person report, conduct a search around the residence, often relying on the assistance of others, and not provide dedicated assistance sought by the family if they do not believe there's evidence of foul play to open a criminal investigation. IMO, LE sees this as a suspicious missing person investigation. We know authorities took Dylan's boots, allegedly found with blood on them for testing, and perhaps the results of the test may change the course of the investigation.
I believe Lucin is located in Box Elder County, an area with limited resources. Relative to the comment on the Official Page that Land Management could be available for assistance, the BLM is responsible for managing all federally owned property in the U.S. Reportedly, nearly half of all land managed by BML is primarily found in two states: Alaska, 29%, and Nevada, 19%. I'm not yet familiar with the territory surrounding this case other than Lucin being located at the NV border but I suspect property managed by BLM is not too distant from Dylan's ranch or the area he's believed to have last been seen.
