The engineer in the gang that tries to steal trilithium resin from the Enterprise-D in 2369, shot by his own leader once the work is done.
Neil is a member of the group of thieves led by Kelsey. He appears in the episode Starship Mine, played by Tom Nibley.
He is the technical expert of the team. It is his job to draw the highly unstable trilithium resin out of the warp engines and into a container that can be carried safely. He is nervous by nature and grows more so as Captain Picard, whom the gang take for the ship's barber, starts to wreck their equipment.
Neil manages to finish the transfer. By then most of the others are dead or missing, and Kelsey sees no reason to share the money. She shoots him and heads for her escape ship alone with the resin. Picard has removed a control from the container, and it explodes soon after she leaves.
