Systems, methods, and devices disclosed herein can collect digital witness statements (e.g., on a witness's own mobile device), detect when witnesses are accessing electronic resources during preparation of those digital witness statements, elicit input from witnesses to identify the electronic resources accessed, and detect portions of the digital witness statements that may have been influenced by data procured from those electronic resources. Furthermore, the systems, methods, and devices disclosed herein can generate an indication of consistency between content found in the electronic resources and content found in the digital witness statements so that a degree to which the electronic resources influenced the witness statements can be inferred.
