>>1131279There really isn't anything that would point that way IRL, not on a just dead body. A container is just a truck trailer you can put on a ship, and most equipment that would have a ship's name/callsign/IMO number on it is painted on. Nobody has that stuff branded on equipment. At absolute best you might have a crime lab be able to find marine paint flakes on her something, but that won't give you the ship or its route.
Your best bet would be to have him find her body in a container, maybe as it's abandoned on its trailer in the back of a gas station like that one example of Mexican trafficking in Texas about 20 years back. Something keys him in that the container came off a ship recently, not just as one of the various containers being used as regular trailers. (maybe she got out to look for food and stole a fire axe for protection and took it back. Bonus points if the coyotes killed her with it and left it embedded in her skull.) The investigator realizes that this was a ship's axe, and then checks the container's S/U on one of the various container tracking websites (like
http://www.track-trace.com/container), and follows its path back to the port of loading.
Or if these particular coyotes are particularly stupid, they could have left the bill of lading still taped to the container when they abandoned it.
