After oral argument and careful consideration, we conclude that the judgment of the district court is due to be affirmed. Appellant’s primary argument on appeal is his challenge to the Guideline section 2Ll.l(b)(7)(D) enhancement on account of the death of one person who was still in the water and was run over either by appellant’s boat or by the boat of the Cuban border patrol. Appellant does not challenge his enhancement under § 2Ll.l(b)(6). That section provides for an enhancement if the offense involved intentionally or recklessly creating a substantial risk of death or bodily injury to another person. The challenged enhancement— § 2Ll.l(b)(7)(D) — applies: “If any person died.”

In this case, appellant’s smuggling operation involved anchoring his go-fast boat offshore of Cuba, requiring the aliens to be smuggled to swim to the boat. Nine aliens had already arrived at appellant’s boat when the Cuban Border Patrol appeared and attempted to stop the operation. A number of aliens had not yet reached appellant’s boat, and were still in the water. When appellant’s boat left abruptly, and the Cuban Border Patrol took chase, one of the persons still in the water was killed.

We readily conclude that the person who was killed died as a result of the substantial risk of death which was created intentionally or recklessly by appellant’s smuggling operation. Appellant conceded that he intentionally or recklessly created a substantial risk of death or serious bodily injury (2Ll.l(b)(6)); on these facts, we conclude that there was sufficient causal nexus between the risk and the death to find that the death resulted from that risk and for the district court to find the enhancement under 2Ll.l(b)(7)(D) applicable. 1

Appellant’s challenge to the reasonableness of the sentence is wholly without merit and rejected without need for further discussion. Accordingly, the judgment of the district court is

AFFIRMED.
