1. A computer-implemented method comprising:
determining that a group of items left a space together based on RFID exit times;
determining that at least one item of the group of items left the space without authorization by evaluating transactions that took place within a time period before the at least one item left the space;
automatically creating a single investigation file that includes the group of items that left the space together;
storing in the investigation file a path through the space that at least one item in the group of items followed before it left the space;
generating a user interface showing a map of the space and a path of an item in the group of items;
receiving an indication that a pointer is hovered over a portion of the path; and
displaying a time at which the item was located at the portion of the path.
