1. Golden Parachute
Megan Donner returns to the CSI unit in time to work on a jet crash in the Everglades. While searching for survivors, they inexplicably discover a female victim found five miles from the crash site.

A shark caught off the coast of Miami contains a human male arm and partial torso with a single .45-calibre bullet wound.

When a matching bullet is found lodged in the hull of an abandoned boat stained with female blood, the CSIs realize that they are looking for another victim. She turns up, dead, in a Russian-issued inner tube. Identified as Elena De Soto, who was attempting to escape from Cuba to the United States, she was shot fatally in the thigh. DNA evidence reveals that whoever tied the tourniquet around her leg was a close relative, probably her brother, Pedro De Soto, who is arrested when a Colt .45 is found in his bedroom.
