As far as I know, the FBI was merely assisting in this case, and wasn’t the lead agency in charge.
I think it’s likely that this guy is in the custody of local law enforcement, and he just hasn’t been entered into the system yet.
I doubt he’s in federal custody.
This shows only the original charges but his mugshot is from yesterday so it looks like he is back where he started.
