The address of the location is 9950 Marconi Drive #104, San Diego CA 92154. You can use Google map and zoom in on the satellite images of the border. Look at where the fence ends about two or three miles east of the tunnel. You can see the foot trails on Otay Mountain from miles away. There is so much foot traffic there every night that the trails stand out. That border in San Diego is supposed to be the most secure sector. No way.
And what is going to happen to the person who owns that property? Probably nothing.
