The T-3 ice island case involved two trials in the United States of a Mexican-American, Mario Escamilla, for allegedly causing the death of a Negro coworker, Bennie Lightsey, on an ice island then at lat 84°45.8'N, long 106°24.4'W, on the High Seas, about 240 km north of Ellesmere Island on 16 July 1970. A federal judge in Virginia allowed Escamilla's first trail to proceed without definitively deciding on objections to jurisdiction, for he expected a ruling on this point on appeal. Issues raised by that trial are covered elsewhere (Pharand, 1971; Wilkes, 1972).
