Once you have the data, it's almost trivial. The data, of course, needs to be acquired through a warrant, which is often really hard to get (which is good) and even then there's a chance it might not exist (logging policies differ a lot), but once you have access to it it's just a matter of running a geofence query and talking to neighbours to get a sense of the criminal's path before the incident so they can identify them in the data. Filtering out everyone who was there 5hrs before and after should be enough to narrow things down to a reasonable level for a human to go through.
