Satler

Trilithium thief aboard the Enterprise-D

One of the gang that boards the empty Enterprise-D at Arkaria Base in 2369 to steal trilithium resin, who dies in the baryon sweep.

Satler is a member of the group led by Kelsey. He appears in the episode Starship Mine, played by Tim deZarn.
While the Enterprise is docked for a baryon sweep, a radiation beam that is deadly to living tissue, the crew leave the ship. Kelsey's team pose as technicians so that they can drain trilithium resin from the engines and sell it. Picard comes back for his saddle and is the only person left on board to stop them.
Satler is one of the armed men sent through the ship as Picard's sabotage upsets their plans. Satler is caught in a corridor as the green beam moves through the ship, and it kills him. His is one of several deaths as Picard picks the gang off.
