Nelson (Maquis)

Nelson was a Human member of the Maquis, a former compatriot of Chakotay and B'Elanna Torres who was slaughtered by the Dominion-reinforced Cardassians in 2374. 

The day after Torres learned the news that all of her Maquis friends were dead, she created the holodeck program "Torres Zeta-1" in which Nelson was slaughtered along with three other of her Maquis buddies, Sahreen, Li Paz and Meyer. The purpose behind this was in order to "feel something," as she otherwise felt nothing at all viewing their dead corpses.
