Josh had some devices confiscated in November 2019 when the search warrant was acted upon. Since he was not charged with anything at that time, he could easily purchase a new phone, tablet or laptop. The car lot was shuttered after the raid. It appears that Josh's illegal actions were happening at the car lot where he brought his RV in and set up his laptop using the internet there. If Josh has been under Duggar house arrest since then, he may have not had the opportunity to do anything else illegal. Josh was "working" at the car lot in May 2019 when he downloaded the files.
