RedactedNarrative: Unit 1 left the marina dock and skippers on Lake Greenwood. Shortly after getting to the middle channel of Lake Greenwood the victim as well as one of the juvenile passengers jumped from the stern of Unit 1. The operator of Unit 1 then slowed the watercraft to recover the passengers in the water. A third passenger then entered the water to recover the juvenile with a PFD while the operator attempted to get back to the victim. Before the operator of Unit 1 could get to the victim he went under and did not resurface.
