N366754 17: Would-be illegal immigrants help one another flee back over the international border fence to Mexico as their crossing attempt ends in failure when U.S. Border Patrol agents rush them near Calexico, Ca., March 18. 2000. At this is section of border fence, illegal immigrants can try to cross into the U.S. without having to swim the strong currents of the All-American Canal or float down the sewage filled New River. Within a week after this photo was taken, the bodies of four drowning victims were found in the All-American canal bringing the total number of drownings in the canal since January to 12.
