I’ve seen past employers contact the FBI for a similar issue, but we had control of the network and logs in question so that made it easier. You may be able to contact interpol or a similar agency in the EU. They will at least be able to tell you the right agency to call.
You can also have a lawyer contact comcast on your behalf. Many times a company will retrieve and store logs in preparation of various legal proceedings. Comcast is a very large company so there’s no way to be sure that this will spur them into action, but it’s a start.
