[@KatherinWinter] Perfectly reasonable, not everyone knows the formal layout of a case file or police report.

e'd likely have an initial police report provided by a mole in the local PD as the main contents of the case file. The rest the agents would fill out with more information and evidence as it is gathered.

Based on my somewhat limited memory, a police report generally goes something like this:

Case number ________________	 Date:
____________________________

reporting Officer _____________
____________________________	Prepared by:

Incident:
---------------------------------------------
[u][b]detail of event[/b][/u]
(a description of when/where/what was reported)
[b][u]actions taken[/u][/b]
(a description of what the responding officer/officers did during the immediate follow-up to the call in)
