>The rifle also requires a license, so they can at least trace where it comes from (even if it isn't his personally, but the general location will help narrow it down).
No it doesn't. It's old enough that there are probably no records, or at least surviving records of its purchase. Or if it was a private sale, there is no record at all. And you do not need a license to own a rifle in Utah.

The FBI probably has a lot more info than they are telling us, and are probably in here trying to guide the convo to certain areas to have us research it for them and give them ideas desu
